Thank you so much. I measured it like you said, on the fpdm, between the white wire and the black/yellow wire, with ignition off. There was 0 volts. Then I asked a helper to turn the key to the on position and voltage between the 2 pins increased to 9.4 volts. This morning I am going out to do all the rest of the things you said. I am getting ready now. I wish ford had put the central junction box somewhere else. But it is what it is, right? I can't begin to tell you how grateful I am for your help.

Not sure if this is my issue as I don't have the proper testers for fuses and pwr. It is my landlord's truck; mine broke down and he said I could put his on the road and use it for work. I paid to legalize it and it never started. Great video, finally not just someone saying hey, your fuel pump is bad lol. Been sitting for 8 months so anything could have happened. 2:30 in the morning and I'm going to just the physical condition of the module.

[@StilesAutomotive]

Papa, Ensure your Battery has a full charge. I assume when attempting to start the F-150 you do not hear the Fuel Pump, The F-150 Cranks and will not start, get a helper to turn the Ignition Key, while you put your Ear to the Fuel Filler Opening (with the Fuel Cap removed), you should hear the Pump Run. Have the helper turn the Key on and off a few times. The Fuel Pump should cycle on and off. If it does not - - 1) With the Ignition Key off, 2) Remove the Electrical Connector from the Fuel Pump Driver Module (FPDM), 3) Using 2 Paper Clips jumper the Positive and Negative Electrical Connector Sockets (like I showed you in the video), 4) Turn the Ignition Key "on" ( and not to "start" or the F-150 may start and run), 5) Go back to the Fuel Filler Opening and listen for a good strong Fuel Pump, 6a) If you don't hear it, it is likely the Pump, but you don't know unless you check Voltage. 6b) If you hear the Fuel Pump, go start the F-150, and it will likely run, you have bad FPDM. Let me know how it goes! - Stiles

Thanks so much for doing this video! My son had his fuel pump on his 2007 F150 about 3 weeks ago, called today and said his truck wouldn't start/fire. After watching this video I had him take the gas cap off and listen for the fuel pump to run when the key was turned - no sound. Took a gamble and bought a new FP Drive Module and plugged it in - started right up! Dropped the spare tire and the old one looked exactly like the one in this video! It doesn't appear this was due to damage as mentioned in the video, it's just a flat out poor OEM design. The replacement module we got has two key improvements - 1) the housing case appeared to be plastic versus cast aluminum, and 2) it now has two rubber bushings to mount between the unit and the axle to keep it from bending/breaking.

Found information concerning a turn over - no start problem leading to the fuel pump driver module under the rear spare tire. Checked this item for failure, turns out the ground wire for this module had broke off from the frame member. Several attempts to re-ground failed to start the truck. After stripping back wire jacket cover and some insulation found that in addition to the ground wire there is additionally a bare wire from the wiring cluster which wraps around the brown/black and the pink/black wires from the module plug, this bare wire is connected to the black/yellow wire which is grounded to the frame. Well my bare stranded wire had 90% frayed/broke away from the main b/y ground wire and looked frayed back to at least 3' as far as I could find while searching along the wire cluster along the driver side of A frame member. These 3 wires brwn/blk, pink/ blk and the bare stranded wire were wrapped in a silver foil like sheathing. I could not find good well insulated wire along this chase so i added a good pc of wire to the largest dia of the stranded bare wire and re-assembled it to the ground wire, taped and siliconed all splices - it worked like a charm! So it was not my Fuel Pump Driver Module YET!

[@StilesAutomotive]

Wilburt, it is amazing your truck ran as long as it did, I'm amazed my truck ran as long as it did with the way the FPDM fell apart. With the condition of your wires, I'm surprised your FPDM is in one piece. Like I say in the video, if you haven't replace the Module, you need to.

[@StilesAutomotive]

Benjamin, If they use salt on your roads, chances are it is the Fuel Pump Driver Module (FPDM). Under any conditions, for a 2004 thru 2008 F-150 with Cranks but won't start condition, the most like cause is the FPDM. Let me know how it goes! - Stiles

[@tourman09]

I have a 2013 E-350 with the same problem, it does start, but only runs for about 10 minutes then stalls and won't restart, just turns over. If I let it sit for another 10 minutes it will start again and run for about 2 minutes. the garage thinks it's electrical, but I tend to think this is the problem. For a $50 part I'm pretty sure I can change it out myself. Thanks for the great video.

[@StilesAutomotive]

Wayne, For F-150s, If your Fuel Pump Drive Module (FPDM) is corroded at all replace it, your E-350 FPDM is not the same, it is plastic, and I'm not convinced it is the problem, it could be, but when it fails it fails. I think . . . did your shop check the fuel pressure at the Fuel Rail? Was it ok? if low pressure your Fuel Pump may be failing. or your Fuel Pressure Sensor on the Fuel Rail could be causing a problem. I showed in the video how to jumper the FPDM Electrical Connector, your Electrical Connector is different, I believe you would jumper the 2 outside Sockets of the 3, then with the Ignition Key on the Fuel Pump will run at full pressure, does your Van start and run, now? If so the Fuel Pump is ok. Yes, it is a $50 part (for your E-350, not F-150s) and I would recommend you pay the extra money for a Motorcraft Part, I don't always, but in this case I do. - Let me know how it goes! - Stiles

[@tourman09]

@@StilesAutomotive My shop, the local Ford dealership, thinks it is electrical due to all the extra wires under my dash, the vehicle used to be a mobility transit van with wheelchair ramp. All wires for the exterior lights and ramp were cut and taped years before we bought it. But I started it up and drove it back from them and had no problem, no stalling. It just started recently and it has been sitting in my driveway. I did buy the part directly from Ford. There has never been any electrical smell at all that I have noticed either.

Nice video! Question, can a bad fuel pump module give me a "crank no start"? I hear the pump coming on but have no Schrader valve. Tried quick start and that was a no also, new battery, camshaft positioning sensors, got about 300 on my tach. checked all fuses & relays, starter switch, safety neutral etc.. I'm lost!

[@StilesAutomotive]

Tom, sounds like no spark. The FPDM can cause a cranks, but won't start, like it did for me in the video. But you say you can hear the Fuel Pump running, take the Gas Cap off, put your ear near it and have someone else turn the Ignition Key to "on", you should hear the Fuel Pump good and strong. Next check for Spark. Sounds like you are doing the right things, Fuses, Relays . . . Did you Truck run after replacing the Camshaft Position Sensors? Power at the PCM? Quick Start is Starting Fluid? (Be careful!) If so this leads me to believe, no spark. Stiles

[@locknload9143]

@@StilesAutomotive ..Thanks for the reply! I just commented on the wrong thread lmao..But anyways, I have spark, and the first thing was changed both camshaft sensors. Finally got it running but, like a bag of cats! Got new codes, camshaft sensors all 14 test drives now along with o2 codes. Replaced the bad o2 (high voltage) cleaned the other 3. Test drive #15 and, same camshaft codes every time. Started to think I jumped time of my phasers are bad. Have no clue about phasers, though that was from star trek lol..Last time I rebuilt an engine was a 350, 25 years ago. Was able to drive it only for short tests due to how bad it's idling my last test drive it died again. Had to get it towed home. Back to a crank no start. But like I said every single tests I keep getting those camshaft codes. Now here's a funny thing, the last three mornings I was able to start it, but only for it to die right away. I started thinking fuel again!? I was about to remove the valve covers, possibly drop the pan and check my timing and phasers. But could a bad fuel module make it run sometimes, but at a very bad idle? Probably a lot easier to test then taking off the valve covers. Any feedback would be great! Once again I appreciate it Eh 🇨🇦 I've had 3 snow storms in 3 weeks, working outside, that's part of my problem.

I'm only getting 8 volts on that white wire coming into the module in the back. I do have 12 volt on the inertia switch. Any idea how to figure out why? My module looks just like yours cracked and broken and I have no start with no sound from the fuel pump on key.. looks so similar to yours even the crossmember funk is the same.

[@StilesAutomotive]

Alex, you could have a bad white Wire, but I think a most likely cause is a dirty Electrical Connector (C3138) on the outside of the frame on the Driver's Side located about midpoint between the Front and Rear Wheels, it is under a black plastic Cover. It may be worth your time to remove the Cover Clean the area and disconnect each Electrical Connector there, Clean with electrical contact Cleaner, and apply generous amounts of di-electric grease to the Connector, then reconnect them. I'd be interested to know if you get 12 volts at the FPDM. Let me know how it goes. - Stiles

[@Larsenvlogs]

@@StilesAutomotive so what I was finding today is I only have 13 volts when I jumper the grounds in that module connector. Which actually I think makes sense doesn't it? If I just try to test the five pin for power I get 7 volts until I jumper the two grounds on the opposite side of the connector together and then I see 13. I assume that makes sence. I'm thinking about just hooking 12 volt power from a battery directly to the pump terminals to make sure.

[@jameskilleen5363]

Thanks think it's my problem rusty 242000 miles from canada

[@StilesAutomotive]

James, of course it depends on what part of Canada you are from. I lived in Fargo ND for a couple of years and they used very little salt on the road in the winter. In most of the Midwest the Road Commission puts a LOT of salt on the roads, which cause a LOT of corrosion on vehicles. The F-150 FPDM is mounted in a position that gets salt on it but doesn't it wash water on it to clean it. As you can see from my video, my FPDM fell apart when I removed it. A word to the wise, if you have 242,000 miles on your F-150 and you haven't replaced the Module, do it as soon as you can. Best wishes for your "rusty problem". - Stiles

Is it safe to drive to the parts store with the paper clip (jumpers) in ?

[@StilesAutomotive]

Mit, I wouldn't if you can find a ride to the Parts Store. Is it just a couple of miles? In my younger days I probably would have tried it. Your Fuel Pump will continue to run with the key on, which will over pressurize the Fuel System. Best case, your Engine will run Fuel Rich. Will it hurt the Fuel System, probably not, it should handle the extra pressure. Will it hurt the Fuel Pump, probably not for a few miles. Will it hurt the injectors or push one open (and introduce excessive Fuel into the Engine?), probably not. In the end, it would be best to get a ride from someone. Let me know how it goes! - Stiles

[@juanibarra2885]

What's the difference between a fuel pressure regulator and a fuel pressure sensor

[@StilesAutomotive]

Juan, a Fuel Pressure Regulator is a mechanical device that control the Fuel pressure by returning some Fuel back to the Fuel Tank. A Fuel Pressure Sensor sends a signal to the Fuel Pump Driver Module to regulate or control the fuel pressure. The Fuel System that uses the Regulator has a Fuel Return Line and the System that uses the Sensor does not. - Stiles

[@paulkuijer8129]

Can I use the car with the jumpers in?

[@StilesAutomotive]

Sutton, The first thing a Military Mechanic asks the Equipment Operator is, "what is the last thing you touched?" I'm trying to think what you could have done, but your problem sounds like a Fuel Problem, not a Spark Plug or Coil (CoP) problem. You commented on my "2004 thru 2008" F-150 Video; First, what Year, Model and Engine do you have? When you removed the Number 4 Coil and Spark Plug (Passenger's Side Back), did you remove the PCM? Did you remove the Electrical Connectors on the PCM? Did you touch the wires on the Electrical Connectors on the PCM. The "let it sit for a few minutes" doesn't sound electrical to me, sounds Fuel or Heat related and you didn't drive it far so, likely not heat. I'd love to know the Fuel Pressure on the Engine Fuel Rail during this cycle of run, die, crank and no start, and run. - Stiles

Brandon, I mentioned this in the video, when I talked about painting the new FPDM. I left the spot where the Mounting Bolt contacts the FPDM Base, un-coated so that if the Module is grounded thru the Base that there would be a good ground. I think that it is. And I think that it will not work properly if not mounted. Let me know if you tried it and what happened. Be sure to coat your new Module to prevent corrosion. - Stiles

When I turn the key to start position I get approximately 9 volts on the white wire from the fuel pressure drive module. Is that sufficient voltage to run the fuel pump? Or is there a voltage drop somewhere that is keeping the (new) fuel pressure drive module from receiving enough voltage to power the fuel pump? Your video is the best one I'v e seen. Thank you one million times. Please help me with this voltage problem. It's like you said, engine cranks but don't run. It's a 2006 ford f150 5.4 litre. I have watched about 30 video's so far and spent a week trying to get this truck to start, including jumpering the 2 sets of outside pins on the fuel pressure drive module, which did cause it to start, plus verifying grounds , fuses, wiring, etc. Again, thank you so much for any help you can offer.

[@StilesAutomotive]

Winter, Glad to help. We want close to Battery Voltage at the FPDM Connector White Power Input Wire, Socket 5. Voltage drop a few tens is ok, that's Battery Voltage minus 0.2 to 0.4 Volts. We want 12 Volts at that Socket. We need to be clear, you said "from" the FPDM, the White Wire is "to" the FPDM. If you are talking about the Brown-White Wire "from" the FPDM and "to" the Fuel Pump, that's different, I don't think you are. How did you measure 9 Volts at the White Wire at Socket 5 and using the Socket 3 (Black Wire) Ground like I did my video? If so you need to measure measure voltage again, using a good ground, use a wire and go all the way to the Battery Negative Terminal if you have to. You wrote about grounds, did you find and clean the ground on the Black Wire at the FPDM Connector? I didn't do this in my video. If you still measure 9 Volts at the FPDM Connector, measure voltage before and after (both wires) on the Inertia Fuel Shutoff Switch (left-side of the Fuse Panel, shown in video). Is all that clear? 1) Measure Voltage at Socket 5 (White Wire) of FPDM Connector using good ground. 2) If 11.8 to 12.6 Volts, goto step 3, if 9 Volts goto step 4. 3) Clean ground at Truck Frame from FPDM Connector and verify Black Ground Wire is ok. 4) Measure Voltage at Inertia Fuel Shutoff Switch (before and after) should be Battery Voltage on both. 5) If 11.8 to 12.6 Volts - likely White Wire to FPDM Connector is bad. If 9 Volts we need to look at why. I look forward to your reply - Stiles

I have one of these trucks in the middle of the jungle in Guatemala and have been fighting fuel pump issues for 3 months now with no success. I managed to get a hold of a brand new fuel pump module but either it's not grounding correctly or it's not receiving commands from the computer. I use jumper wires on the connector pin two to five and three to four like you say in the video and the truck starts and runs. I left it in there and tried to drive down the street but after 2 or 3 times maybe 10 minutes total running the brand new Bosch fuel pump burnt out. Is it safe to assume that the fuel pump was under too much stress because there is no return line? Is there no way to Jimmy rig this thing to work? I'm on dirt roads in the middle of the jungle maybe 15 mile per hour max speed, I'm just looking for a way to make it start.

[@StilesAutomotive]

Alex, You didn't say the model year and engine of your F-150. The Fuel Pump Driver Module (FPDM) pulses the Fuel Pump on and off to regulate the fuel pressure. Yes, if you run the Fuel Pump continually with no pressure regulation your Fuel Pump will likely prematurely fail. Your new FPDM grounds thru the Mounting Bolts to the Truck crossmember. Removing the Bolts and reinstalling them on a new FPDM likely has a good enough ground, however, you should remove it and clean the Mounting Bolts, new FPDM and the Crossmember at the mounting location with a Wire Brush. You should clean the FPDM Electrical Connector (like I did in the video) with Contact Cleaner and use Dielectric Grease on it. With that said, I think your real problem is . . . You didn't mention any fault codes or Check Engine Light . . . and you should have for this problem . . . but, I believe you have a bad Fuel Injection Pressure Sensor, (below is the link to the Rock Auto Page for my 2005 F-150 5.4L Sensor, buy/order using your Truck information). This Pressure Sensor is located on the Engine Fuel Rail, Mine is on the Leftside (Driver's Side) of the Air Filter Housing, behind the Power Steering Fluid Reservoir. You should normally get a Fault Code for this sensor, but maybe you didn't. When you replace it, again, clean the Electrical Connector and apply Di-electric Grease. Next, if the above didn't fix your problem, Clean the Electrical Connector(s) (I need to do a video on this, but have not) under the Plastic Cover on the outside of the Frame on the Leftside (Driver's Side) of the Truck. These Connectors, joint the Rear Harnesses to the Front Harnesses on the Truck and can became corroded. You should clean and Dielectric Grease these some day, anyway. Even if you fix the problem. There is more, if you still have a problem you need to clean the Grounds and Electrical Connectors on the Powertrain Control Module (PCM). The PCM is located in the Engine Compartment near the Battery on the Firewall. Be careful, don't clean the Connectors if you don't need to, you could damage the PCM Connector Pins. But, Someday if you replace the Battery, clean the PCM Grounds with a Wire Brush and coat with Anti-seize. If it comes to cleaning PCM Connectors, do a continuity check on the Signal Wire from the PCM to the FPDM, these are the 2 smaller wires I point out in the video. There is not a easy way to jerry-rig or bypass this system. Let me know how it goes! - Stiles www.rockauto.com/en/catalog/ford,2005,f-150,5.4l+v8,1431304,fuel+&+air,fuel+injection+pressure+sensor,6376

Lou, I'm not sure why your Fuel Pump didn't run, I showed you the 6 Pin Connector in the video and if you have Battery voltage at the FPDM Connector, your Fuel Pump should have run. Your Fuel Pump could be bad, HOWEVER, this is much less likely. This video is talking about the 2004 thru 2008 F-150 and if you have NOT replaced your FPDM yet. I highly recommend you doing so. Even, in the event you find the Fuel Pump bad. 1) Make sure you have Battery voltage at the FPDM Connector using a Volt Meter, should read 11 to 12.6 Volts. If you don't you need to find out why. 2) Make sure you have a good Ground. Measure continuity to Ground. 3) And . . . make sure you inspect the FPDM Wiring Harness from the Truck Frame to the FPDM. Make sure it looks good and re-rap it with Electrical Tape. Let me know how it goes! - Stiles

Military Vehicles experience a harsh environment depending on which deck they are on. I would expect your F-150 would be treated better, but still be subject to moisture and salt air. I believe you are correct when talking about a Reset Switch, which is really a Fuel Shut-Off Switch. Your 2009 F-150, is not like my 2005 F-150, I have a Physical Shut-off Switch, you do not. Your F-150 is similar to my 2013 Mustang. I believe your F-150 experience a bump which may have triggered this Fuel Shut-off Feature. Reference your Owner's Manual Page 313 & 314 (I copy it here): FUEL PUMP SHUT-OFF In the event of a moderate to severe collision, this vehicle is equipped with a fuel pump shut-off feature that stops the flow of fuel to the engine. Not every impact will cause a shut-off. Should your vehicle shut off after a collision due to this feature, you may restart your vehicle by doing the following: 1. Turn the ignition switch to the off position. 2. Turn the ignition switch to the on position. In some instances the vehicle may not restart the first time you try to restart and may take one additional attempt. Also, because your Truck is similar to my 2013 Mustang, my Mustang Video will help you: Mustang After Accident, Fuel Shutoff Procedure - 2005 thru 2014 Ford Mustangs kzbin.info/www/bejne/bmixlZt8e7KSgsU If this doesn't do it, your Mechanic needs to determine if the Fuel Pump is Running and you have fuel pressure at the Fuel Rail on the Engine.

[@StilesAutomotive]

Vernon, Sorry for the late reply (I normally get to your type of question with in 24 hrs), I was down range. The Spark side (and PCM side) of your problem, often results in a OBDII code, but the Fuel Side (ie Pressure Sensor, Fuel Pump Driver Module and Fuel Pump) does not. Intermittent problems are hard to diagnose, I'd love to know your Fuel Pressure at the Fuel Rail. 1) Fuel Pumps can get old a flow less fuel, but normally don't fail this way, they stop all together. 2) Like I stated in my Video that you are commenting on (and the reason for the video) if you haven't replaced your FPDM, I'd do so, but You need to pay attention to the wires (intermittent problems are very often broken wires or bad grounds), remove the Electrical Tape and Harness Wrap from the Driver Module to the mounting location on the Truck Frame and inspect the wires, clean the connectors, re-wrap them with Electrical Tape. 2a) on the Left (Driver's) Side Frame (and on the outside of Frame) and mid-way between the wheels is a Plastic Cover that protects Harness Connectors, clean the connectors there. 3) You have a Fuel Pressure Sensor on the Fuel Rail on the Engine. It could be going bad or maybe dirty, in either case replace it. For the FPDM and the sensor, I would only use Ford Motorcraft Parts. Use a lot of a good connector cleaner like this one: QD Contact Cleaner CRC amzn.to/3DKfOQ3 Let me know how it goes! - Stiles

[@StilesAutomotive]

David, You have to be more specific for me to help you, You said "it is still a crank/no start" then in the next sentence "still couldn't crank". A crank and no start condition means the Engine turns over with the Starter, but the Engine fails to run or fire. This means you are not putting into the Engine: Air, Fuel or Spark, (assuming no other mechanical failures). Air is easy and likely not the issue unless the Truck has been sitting a long time. Fuel or Spark, you are working the Fuel Side if looking at the FPDM, Yep replace it if corroded at all, clean the Electrical Connector and grounds, check the Wiring Harness to the FPDM (from Frame to FPDM), check Fuel Pressure at the Fuel Rail (with the FPDM connector jumpered like in the video), if low Pressure, Fuel Pump is at Fault, if good Pressure, Fuel Pressure Sensor on the Fuel Rail is likely the problem. - Stiles

Erad, Makes me wonder how much Fuel you have at the Fuel Rail, Can you get a Fuel Pressure Gauge and read the pressure at the Fuel Rail?

If it runs, your Fuel Pump could be weak, (I don't know what it sounds like), has your Fuel Filter either been replaced?

What happened after you overheated the engine, you drove home . . . Truck hasn't started since? What you say in your other comment is true, just 'cause the pump runs doesn't mean you are getting sufficient fuel pressure at the fuel rail, however, you can tell a lot from the sound of the pump. You can tell if it is strong and hitting hard, or if it is slow and laboring. Often when the fuel pump fails, it fails.

It is a PCM fault or a sensor telling the PCM not to fire (or a bad wire). - Stiles

My 54 Triton starts runs for about 5 seconds and then turns off

[@StilesAutomotive]

Paul, Sounds like a fuel related problem, if it was electrical it wouldn't run at all. Pressure Switch on the Fuel Rail, Fuel Pump, non-venting Fuel Tank, unlikely but Restricted Fuel Filter. Let me know how it goes! - Stiles

[@nickcallahan2669]

I followed the video and did the same thing. Now I hear the fuel pump coming on, but the truck still won’t start.

[@StilesAutomotive]

Nick, you are not giving me much to go on. You have to give the Engine: Air, Fuel and Spark. Do you have Spark? Do you have Fuel at the Engine Fuel Rail? Did you have any noises when your Truck started the No Start Condition? A noise like the Timing Chain Jumping a Tooth? Anything? Was you Fuel Pump not running before? Did you replace the FPDM? If these 2 things are true, you likely have Air in the Fuel System. Cycle the Fuel Pump on and off 6 or more times. - Stiles

[@nickcallahan2669]

@@StilesAutomotive you’re right sorry I was in the middle of a frustrating diagnosis I have spark, the fuel pump wasn’t running until I put the jumpers in and now it runs with the key on. Cranks over strong but no start. Going to double check that I have fuel at the fuel rail !

[@villainvaldez509]

I got same problem but 03 cadillac truck i cannot figure out wtf it is starter good because it cranks battery good all lights turn on it has oil i hear the fuel pump and i was just driving the truck turned it off went and got my niece from school came back out to truck got in and took off about a half mile down the block it died wouldnt start back up fuses and relays are good like wtf lol

[@StilesAutomotive]

Villain, that sounds like a fuel or spark related problem, because it just died. It also sounds like you are doing the right things, checking Fuses and Relays. Back to Basics: for a engine to run you must put in Air, Fuel, and Spark. Unless the car hasn't run in months you know it is getting Air. Spark you can check at the Spark Plug. Fuel check Fuel pressure at the Fuel Rail. You didn't mention any Check Engine Lights or Fault Indication. This might lead you to a Sensor Failure or other indication. Did you hear any noises at all prior to the Engine dying? if no, ok, but, if yes, could be something more serious like Camshaft Timing. Let me know how it goes! - Stiles

[@villainvaldez509]

@@StilesAutomotive no noises at all never had a problem with the truck at all it started for a second then died it wants to start again but wont which makes me think its the fuel pump i put little gas in incase my gauge is faulty still nothing im pretty sure its the fuel pump though ill keep u updated after i replace it

[@villainvaldez509]

@@StilesAutomotive okay update lol so got a fuel pump installed it replaced the fuel filter put new relays and checked fuses it started up finally and drives but its still dyeing when driving and guess what now my 2002 Denali is doing the exact same thing but the starter relay was busted when i move it the truck cranks wont start kinds weird so went and bought a new relay now it wont even crank but all the lights go on on the denali this is BS lol

[@pauldixon8609]

What if it starts with old one but not the new one

[@StilesAutomotive]

Paul, Can you verify you bought the correct part number? I know there are several Ford Part Numbers of the FPDM that look similar. I don't know if they are different generations of the same part, but think that are different FPDMs for different Ford Vehicles. If you have the correct part, look for bent pins on your new Module. I don't think the Module grounds through the base of the Module, so that shouldn't be an issue. I'd be interested to know if the old Module drives (or turns on) the Fuel Pump continuously. This would mean it failed on, and you may not be receiving a signal from the Powertrain Control Module (PCM). Let me back up to verify. With the new FPDM the truck doesn't run, but if you go back to the old FPDM is does run again? Or, it did run with the old FPDM, now doesn't run with either the new or old FPDMs? For the first case, this is what I was talking about above. For the second case, you likely blew a fuse and need to check fuses 34 (20 amp PCM Power) and Fuse 5 (7.5 amp PCM Keep Alive). Hope this help, let me know how your troubleshooting goes. - Stiles

[@donnieblack6852]

Replaced module still won't start only starts with jumper wires

[@StilesAutomotive]

Donnie, That tells me the most likely problem is the Fuel Pressure Sensor on the Fuel Rail on the Top of the Engine. It could possibly be a Wiring problem or a problem with the Powertrain Control Module, but not as likely. Did you make sure the case (the body) of the new FPDM is well ground to the Mounting Point on the Crossmember? Is the Electrical Connection on the FPDM ok? no Pins bent? - Stiles

[@aleksf01]

I have this problem, but my pump does click.

[@StilesAutomotive]

Alex, My truck was running fine until the fuel pump didn't run at all. When the FPDM fails it can cause intermittent engine problems and a fault code in the OBDII display. My truck did not indicate any fault codes and from my video my FPDM broke in half and smaller pieces when removed. - Stiles

[@gd2213]

this part whats name please

[@StilesAutomotive]

Gurmeet, this part is the Fuel Pump Driver Module or FPDM. Look in the video description for link to the Amazon Page for more information and to purchase. - Stiles

So, I finally got the inertia switch out last night, by hanging upside down off the passenger seat. I think I now need to go to the chiropracter. I couldn't actually test the circuit because everyone went home and there was no one to turn the ignition on. Today, hopefully, I can finally accomplish the mission. I'll let you know what happens.. Thanks again for the help. I'd like to freind you on facebook, if you don't mind leaving your name

[@StilesAutomotive]

Winter, you didn't tell me the whole story. Did you determine the Inertia Fuel Shutoff Switch is bad? What voltage did you get at the Inertia Fuel Shutoff Switch? Did you measure voltage at Pin 5 of the FPDM Connector (Black Wire) and go to a good ground? I recommended NOT measuring voltage across Pin 5 to Pin 3, but going to a good ground (like all the way back to the Negative Terminal on the Battery, if you have to). - Stiles

[@winter4345]

I could not get a voltage reading on the inertia switch. Oddly there was no voltage before it and none after it. I bench tested the switch and it was bad (open). I splice the 2 wires to it together. Then I jumpered the 2 sets of the fuel pump drive module together and the truck started and I drove it home. Now, this drive module was brand new, but looking at it closely I realized that it wasn't completely together. Now i know. Thank God. I can't even begin to tell you how much i appreciate your help. Thank you a hundred million times! Now I can finally get my life back. :)

Bebo, I wonder if that isn't a grounding problem. I'd clean (with a wire brush) the FPDM base, the Mounting Point on the Frame, and the Bolts. Have you had any luck fixing your truck? - Stiles

Sogent56, You may have a "Cranks, but won't start" condition, but your Fuel System is different. You have a Fuel Pressure Regulator which controls the fuel pressure. - Stiles

[@dieseldabz7104]

Do those manifold gaskets ASAP man before your heads JUNK! I've become somewhat of a "pro" at fixing them for customers who attempted the job themselves ONLY to snap off studs in the heads. Also the leaking exhaust gas will eat away at the head itself and when that happens it's garbage.

[@StilesAutomotive]

Yes, very true, I think about exhaust gases hurting the Head each time I drive the F-150, seems like the Gaskets rarely leak on the Exhaust Manifold side, but leak between the gasket and the Head which is hard on the Head. I drive a Mustang in the summer, but need to do that Exhaust Manifold before winter. Thanks for the comment! - Stiles
