Ford Quick Tips #80: Common Fuel Pump Failure Points Explained

[@FordTechMakuloco]

A quality Fuel Pressure Gauge is invaluable when diagnosing these concerns- amzn.to/2xDt5Gs Spectra Premium is a great Aftermarket Pump- amzn.to/2gBx40r Fuel Sending Unit failures explained- kzbin.info/www/bejne/l3LVl4iqlriCj8k Here is the original Hybrid diagnosis video that this fuel pump came from- kzbin.info/www/bejne/eoKafmd6opmfhdU

[@annettesanchez2849]

FordTechMakuloco hey good day. Any ideas on a 08 ford fusion. Wont accelerate no codes we replaced the intake and still no luck thanks love ur vids !

[@nicke2307]

Check for a plugged exhaust

[@lovekrew4542]

I would try a cheap vacuum gauge to check mechanical first...then go from there

[@heminow9342]

Will you do a goes explorer ball bearing if i can get the vehicle to you I will pay

[@Duganoz]

This just solved my issue on Escape 2016 with 1/4 tank of fuel.

[@baxrok2.]

Awesome diagnosis and explanation. Your depth of knowledge is impressive. Thanks for sharing all of the details on this one!

[@lovekrew4542]

What gets me is just how HUGE this pump was when I took it out of my 2006 F150 5.4 and it was eating big current at right around 13 amps! Seems like alot but its good pressure and volume... not the problem.Like your video here. Thanks

[@thesteaktc]

Really interesting video, thanks for posting. I hope I never have fuel pump issues.

[@JaMarvelousjmar]

I got nervous when I saw the pump start to lean. First thing came to my mind was water and electricity doesn't mix. You are an excellent instructor. Even though my '05 f150 runs like a bucking bronco. I'm gonna try to tackle the tune up myself. Thanks for the videos

You are not intelligent. Just indoctrinated

[@OgunjobiDavid]

Thanks for this awesome high tech experimental demonstration I think it explains perfectly what is wrong with my ford fuel system Thank you

[@癲子圍觀]

It's not a basic knowledge, it's a professional explain,,,2👍👍

[@raymondboots6089]

Bad design, I hope they corrected the problem. Thanks for the video. Another one for the books. Have a great one and thanks for the education again.

[@petemoss9693]

Very good anonymity of how a Ford fuel pump works - thank's for sharing this video for all of us .

[@jerrystahl9675]

Great job thanks

[@1tarik]

This dude know what hes talking about 👍

[@Jimmynitr]

Good stuff, informative and much appreciated

[@gury0771]

since am ford user for years, you absolutely correct 👍👍👍👍

[@bkp8345]

Absolutely fantastic video. Maybe this is my issue on my 2013 focus. Replacing the pump today.

[@user-ky7ty3ie1x]

Hi what issues did you have with your ford what engine did is start

[@bkp8345]

@@user-ky7ty3ie1x I replaced the fuel pump. Worked great after that. I also cleaned the internal circuitry of the throttle body. I checked for carbon build up on the valves, there was none. So fuel pump or the throttle body circuitry cleaning did the trick.

[@x-man4702]

Great educational video! Thanks for posting.

[@patrickregan8623]

Enjoyed your video thanks for taking the time to explain.

[@clayrowe9111]

I have a 2018 f150 that I think my fuel pump has went out. I pull the truck in my shop and and the truck started sputtering and shut off now it’s cranks but want start. I can’t here the put prime in the tank. What your thoughts??

[@marshellli8107]

I currently have a 2023 ford maverick (EB 2.0), and I notice the HPFP is getting louder compare to when I first got it, and I noticed some strong gasoline smell from the engine oil cap. The dealer said everything is normal and within the "normal" range :(. I was thinking about to change the HPFP to the Bosch one, and would you recommend to do so? Also, without removing the engine, is it still possible to crank the engine to the "flat" spot when installing the new HPFP? Thank you

[@hectorlopez7223]

Awesome videos man! I have a 2018 F150 Raptor with a stalling issue when the engine is warm. This will only happen when the vehicle has reached normal temperature, no issues while driving, no loss of power, no check engine lights. The issue comes in when attempting to start the vehicle after has been used for a couple of miles. Been to three different FORD service departments still having the same issue. Not much information on forums for this exact issue. I would really love to pick up your mind on this scenario. Been dealing with this issue for about 6 months now with no check engine lights. Putting my thoughts together I do remember this issue started after running low on fuel for a couple of miles before getting into the gas station. Also if a park on my driveway nose down it would start with a rough idle but will NOT die. When parking on a level surface or nose up it will die immediately and sometimes it'll give me a long cranking. All this is only when the engine has reached normal temperature. In the mornings when the vehicle has sat the whole night, it will fire up perfectly no matter the angle or position of the truck.

[@Alexander-tg3ys]

My 07 explorer is doing this there is a temp sensor that is 20dollars and may be the culprit not allowing the engine to start I'll keep you posted

[@michael931]

After the dealer did the SAFETY PROGRAM 16S41 recall then my '12 Escape has the exact long crank hard start that they describe in the actual recall. But that dealer is 2 hours away and the local dealer says they won't fix the other dealers problem even though it is a recall. They think it is from nicked barbs on the hose connection. Do you think I can fix it with some fuel resistant RTV? Thanks

[@topgun52]

I really would have liked you to take the pump a part to see what was causing the pressure relief valve to stick, I bet it was a piece of plastic or something that came loose after being manufactured since it took about a year to malfunction. Also, since it partially works should be an easy fix. If you still have it, go a head and take it a part it's just a few screws. Curious minds want to know.

[@dannypalmer7701]

Your the best i trust and i learned alot from you

[@cofty]

Brilliant diagnosis thanks for sharing

[@kwd57]

Can you do a video on cars that don't use external replaceable fuel filters? I am curious where all the dirt is going.

[@gregorytolson4621]

Yes please!

[@vinnyjay89]

how to replace internal fuel filter thanks!! good work.

[@artk749]

Hi I changed my fuel pump and fuel pump driver module works good two years ago on my 2005 ford expedition but anytime I run my fuel tank down to quarter tank remaining it messes up the fuel pump again I replace the fuel pump works good again but only when I run my fuel tank down to quarter it messes up the pump again what causes that

[@AMERICA_F1RST]

Very informative

[@癲子圍觀]

Thank you help many family mechanicals...

[@rustyshackelford6900]

Another excellent video!! I have a 04 f350 dually with a 5.4 that has been sitting for about 5 years. I tried starting it and no go. It will start with starter fluid, so I'm pretty sure its a fuel supply problem. Ran fine when I parked it. Also, California fuel. Any checklist to start trouble shooting?

[@spinb]

This is great information on how these pumps function. Unfortunately, it's all academic. They really need to stop putting the entire fuel pump in the tanks, or at least give us easy access.

[@ozzstars_cars]

Shame it only lasted a year. Nice demo on the problem

[@DeepSouthernTX]

Is it worth just changing this pump's pre-filter since these cars don't have a regular maintenance in line fuel filter?

[@jamesbesharse6810]

Thank you for the info. Always enjoy your videos. Early this year you did one on your 2009 Escape temperature blend door motor. You said you need to replace it. Do you know when you might make a video about doing that?

[@niceguy192]

This a Toyota related question.. so you can answer if you want ☺️ but the pump is almost the same setup. I have been doing my own testing on a hard start issue and when checking the pump I realized I didn't fasten it down properly and fuel was spraying out at the top where it wasn't fastened right. My question is, is that right? If the pumping (sucking/ pumping) happens at the bottom why would file spray out at the top? Could it be a break in the line? Actually I would really appreciate it if you would answer me.

[@heycoolbeats1872]

Thanks for the great vids!

[@RustyRagwing]

Another great video for us Ford Owners! Experienced this noise on my villager minivan. Now I know what it was. LOL Now how about going a bit further and dissecting the pump to show us why the valve id sticking?

[@KarmaVoyager]

How about going a bit further and not owning another ford?

[@RustyRagwing]

LOL Have no complaints about Fords. This one went 323K. Biggest pain was changing the rear injectors since it had a 3.3 V6 Nissan engine. The 3.0 Sable before it went even even further!

[@rrmech11]

Excellent explanation

[@GCraigmile]

Wow!!! I have seen this on a VW' Jetta... Same trouble

[@mikehannahs]

I’m wondering if you would be willing to give me a few pointers, my son has a 1988 Ford F-150, it has sat for around 7 years, really bad gas and all the problems that come with it, we have done the common things such as cleaned out the gas put new in, premium even, lots of fuel system cleaners, filters and pumps, it keeps burning up the high pressure fuel pump, so we put a brand new tank in with another new in tank pump and new high pressure pump, they just keep burning out, it runs for a good while then shuts down, I’ve noticed that the high pressure pump is getting pretty hot, any suggestions? I’m at my wits end with it

[@sotos1301]

If only I knew all this earlier.... I have replaced 3 fuel pumps in my Mondeo MK4 during a 10 year use ....At least one of these times maybe a fill up of the tank would do the trick

[@unorthodoxdaytrader8823]

need help ford fusion 2013 started fine after fill up went home woke up drove like 20 miles drove down a steep hill and car cut off and will not start back up ..its been a week and it still wont stArt it only cranks can some one please help?

[@conantdog]

Help you must know something about the cracking of stainless steel fuel lines on 2012 escapes !,, Ford parts guys say there on interstellar back order. Yet they never sell them ,hardly..never seen them Crack either ! I'm going to cut and splice in fuel hose if I can cut it with a tubing cutter. The two hairline cracks occurred where the pipe contacted at the plastic snap clip mount exactly. No bend or impact damage to pipe that I could detect as a cause for fracture. I'm thinking bad mounting stress on pipe as a cause ? What have you experienced with stainless steel fuel line repair in general and the Escape? Thanks you videos are excellent !

[@steveo782812]

That's an awesome video.

[@marke6196]

Update. Started the van today and disconnected the maf harness clip while running amd stayed on. Drove local for about 5 miles to warm it up. All that showed on the obd reader was the maf codes because it was obviously disconnected. The p0303 and P0171 codes never came back on. Afer the 5 miles I reconnected the maf and drove hard for another 3 to for miles and ran completely fine with no check engine light. Any thoughts what could be the culprit? Maybe the coil pack is cracked and after so many miles of heating up it starts to misfire? Has brand new plugs and wires. Fuel filter clogged? Egr valve clogged with carbon build up? Sprayed brake cleaner along all vacuum lines and gaskets. No sounds i hear. Weird. Appreciate the feed back. 98 Windstar 3.8 limited 4 speed w/ OD

[@conantdog]

Oh did I say the set of fuel pipes Ford sells together only is 299.00 retail 234.00 jobber price. The location of the cracked line is approximately under the drivers seat on the escape. Also recently through drivers side cooling fans blades started cracking from age and losing prices of the blades.

[@zekemontgomery6678]

We have a few fleet f250 2017 and above 6.2 and two in particular have hard staring issues. Takes a few extra secs to fire. Took it to ford deal and they said that was normal? I don’t believe that is correct since mine doesn’t. Wondering if the check valves are bad in the fuel pumps. Have you came across this issue with the later model f series trucks?

[@hoborosser1785]

COOL GM has the same issue I have seen on on a brand new pump :( I have also seen the fuel pressure at 100 PSI when the regulator sticks.

[@toddpeters9007]

Good info thanx

hi can you tell me what voltage i should have on the pump in my s max 2.0 tdci, because i checked and i have just 5V on the connector and my pump is not working at all, btw one of the hose from dpf i have snaped and this could be problem that my car wont start??

[@ronhobyak9902]

Had my car in the garage since around 2018, Started it and pulled it out to the driveway. It has been sitting all summer. Charged the battery and it got hot, It kicked the starter over ok but car didn't start. Battery dead won't take a charge. Battery was 2005. Replaced battery with new one. Cranks starter ok and sputters but won't start and run. Put 5 gal fresh gas in tank over half full. Seems to run spraying carb cleaner into intake but doesn't run. Checked 15 amp fuse. Removed and put back relay. Gona try reset inertia switch. Do you think it is weak gas? Or Fuel pump fail? Or clogged gas line / fuel rail? Could my computer be zapped from charging battery and over heating? Am I missing something? Tried in park and neutral. Pressed inertia switch it clicked but car still won't start. 2004 Ford Focus Wagon ZTW 3.8 - 4 cyl. Swapped high beam relay with fuel pump relay. Still won't start. Help THNX

[@ronhobyak9902]

@André Got it to start by pounding on the floor shifter. It has a switch at the bottom of it and was not engaging. It has to sync with the brake and the key to let the car start.

[@micahcarr4642]

But how was the PCM responding to no fuel pressure at the rail? Mine is sending a 75% duty cycle to the fuel pump to have it shut off? Does that sound right?

[@nchilo]

I have 2006 Ford f-150 STX 4.2. Can you tell me wheres is the valve for fuel pressure tester? Thank you

[@waltermontoya8212]

I would like to see if you can tell me what would cause a fuel pump fuse to continuously blow. The brief description is when I put the key in the ignition with the battery being charged up by the battery charger / booster the fuse blew three times. Is there any other helpful information you might be able to share with me on what could be causing the fuel pump used to be blowing like this sir?

[@waltermontoya8212]

Now the vehicle that I'm working on is a 2005 Ford 500 with the duratec V6. I did put the battery chargers last jumper on it, it fired right up then ran 10 minutes then died as I press lightly on the pedal. It was until after the second time that I got it started that I noticed a fuel pump fuse blew. I then replaced the fuze 2 times and those fuze's blew as well.

[@zdeneksafranek3851]

Hello, I would need advice, I have the F-150 5.4 triton 2004, and I am running out of speed of the engine. CHECK lights up, and the diagnosis writes a poor mix, but obviously everything works electrically. When the accelerator accelerates from the idling speed, detonation is heard in the suction line. Otherwise, in the high swaths, everything is no problem. Do you have any experience what could be damaged? Zdeněk Czech Republic.

[@nicolas.silvestre]

This is great! Could you please tell me where the Fuel Filter is located on a Mondeo MK4 Ecoboost 2.0 (240cv)? How frequently does it need to be changed? Thanks in advance! I love this channel.

Buddy, I have this explorer 2013, came in with abs lights n skid car light on, and they were like they had this light & an electrician scan and advised them to change the abs module, they got new abs module thrown to the car but yet we’re like the old code resurface again, and that is U3000. In the abs, I further asked them what happen or did they carried out any repair works before this symptoms appeared, and they were like this abs light wasn’t ON until they had the steering rack asst replaced and drove a couple of miles then BAAM the abs lights n skid appear, so I am push to conclude that could be their old abs isn’t bad but could be the steering rack, now here is my question, does the rack need programming, if yes, what about the new abs module too, and can you share some steps involve in coding the rack,

[@njmaag]

[@billbethel8375]

Just installed a fuel pump on my sons 2002 Taurus... looks the same as that one. Easy install. Bought the pump on the net for $56..... I hope I didn’t make a big mistake by installing a cheap one. It looked the same as the one I removed .... The one at the auto parts was $286. Hopefully , my savings was not in haste ???????

[@bobr2959]

I'm facing the same situation. I Have not bought a new one yet. Wondering how it's performing even though this thread is closed or old right now. Sure would help me make a wise decision. I have an 1994 E-250 that needs a pump. Tempting to save that much money but is it worth it? Thanks.

[@felipefraire8903]

Bro I have a 2006 ford and am think in bout trading it in just cause of the spark plugs blowing out and the rocker roller problems. That these trucks can have.. but how common is the spark plug blow out and should I change my rocker roller I bought the truck used with 107000 miles and it runs great just worried if it will happen to me and not sure what maintenance the previous owner did..

[@GaryH-pw9cm]

Well today I had a first time for everything moment. I went to replace a fuel pump on a 2014 Expedition but there was a problem. I was taking out the old pump, but the pump housing would not fit through the hole on the tank. It took me an hour to get the pump out of the tank. It seems the material the pump housing was made out of had swollen up to the point I had to fight the thing to finally get it out. I have never seen this before. May be faulty materials, but it is a factory Motor Craft pump. Maybe bad gas or other additives. Finally with the aid of several screwdrivers and a lot of pulling it came out. I installed a new Motor Craft pump and it fit no problem. May be someone has seen this before and knows how this could have happened. Update: I have since found other videos and comments stating the same problem. It seems the 2010 to 2014 Fuel pumps have this problem where the material the fuel pump module is made of expands over time when exposed to fuel. Which is normally not a problem as it is taken into consideration during design. However, in this case someone seems to have dropped the ball during the design of the fuel pump assembly and did not take into consideration that the body of the lower assembly over time can swell to the point it can't be removed without much effort and a lot of bad words being used. The replacement pump is a new Ford Motor Craft pump PFS-579-1X, I used a pneumatic die grinder and a burr tool to cut away the edge on one side of the lower assembly so it can't get caught on the opening of the fuel tank when removing in the future. I hope this helps to be made aware of the problem.

[@82lowe36id]

My 2007 Expedition EL has a crank , but no start now. No fuel pressure at the rail and fuses and relays are good. My wife runs the tank until almost empty a lot. Would this being repeated be hard on the pump and cause it to fail finally?

[@richarda996]

The pump requires a certain amount of fuel to run normally. Without the fuel to cool the pump it runs hotter requiring more current draw leading to fuse failure and cooking the blades.

[@junitoamadeo3296]

I have a fairly new car with very few miles and when i bought it, i ran it out of gas with about 40 miles showing on the trip indicator, about 1/8 tank. Tow truck came to give me a couple gallons and i was on my way. about a month later it died on my way into work. It was running like shit and finally gave up as i was making my way onto the highway ramp. It has about 1/4 tank, and it DOES have fuel to the high pressure rail, i just don't have the correct adapter to test the pressure. i wonder if i got shit pressure...... I've been chasing a no start problem all winter long, and i havent given much attention to the pump because i can confirm the pump is working, but ill bet its not working as good as it should. im going straight home to A: empty my gas can into the tank to see if that gets it to start B: figure out exactly what i need to make a custom rig for a fuel pressure reading! Thank you for the video. Luckily, i do believe i can reach my fuel sender right under the rear seat, inside the cabin of my car.
