DODGE RAM 1500 CRANKS BUT WON'T START DIAGNOSIS & FIX

[@ADVANCEDLEVELAUTO]

The owner recently told me that she drove over an embankment a couple of months ago. She said the truck had to be pulled out by a tow truck because the frame was sitting on the ground. I believe the gas tank may have taken a hit during that incident and that is what broke the fuel pump hanger. She must have been driving a couple of months with the fuel pump module just swashing around freely in the tank. I'm thinking that when she had to stop abruptly, the fuel in the tank swashed around hard enough that the fuel pump got disconnected.

[@jovangrbic97]

Yo hermano just pack that old pump in the delphi box, it probably still works, throw it on Marketplace for 250 and rake in some extra plata. Saludos de Guatemala!

Hey Eric.I have one question for you. I don't know why you put your email on the website that if anybody have a question they can contact you. It look like you want to reply what favor you. Don't worry about it thank you for your time

[@mikesabin8568]

You can use the power probe to load test a ground without using a test light… the instructions that come with the power probe tell you. So you touch the tip to ground, then you hit the power button. If there is a good ground, it trips the circuit breaker. It says that right in the instructions manual. Power goes out of power probe and if it finds good ground, trips that circuit breaker, boom, done

[@Garth2011]

Great diag process vs. buy expensive parts hoping for a fix. Those Delphi parts are top quality. Delphi makes GM oem parts and has for decades. No worries with the Delphi brand ! In this case, the entire fuel pump module makes sense but in many fuel pump jobs, I see mechanics opting to replace the entire module assy rather than just the fuel pump itself. I bring this up because the fuel pump itself, if it is offered separately as a replacement part, usually costs $40 or so vs. the $200 and up prices for complete modules. There's only a tad more labor involved to transfer the existing pump out and install the new one. Keep your fuel line tool with your fuel pressure gauge at all times. Also, its a good idea to recharge battery jumpers each day as a routine to avoid a useless tool when needed. Thanks for sharing your good skills.

[@ufartface]

good point- thats what i did

[@Joserocha-wm9de]

The fuel pump was just hanging by a " thread " and when she slammed on brakes the " wave " created by gas inside the gas rushing to one side of tank was enough to destroy it inside ... You are a master 👌👌

[@cyberslacker5150]

Great Video Eric. At first thought I thought the problem lied in the TIPM relay. A common failure point. But I see that this truck had the Relay Bypass fix done. I think the Relay on the side of the fuse box is the new bypass fuel pump relay. Oh, and I would like to have seen if the old fuel pump motor was working. Maybe it was the connector that became unplugged. However the plastic on the module assembly was broken and even if the pump motor was working, maybe the module assembly was beyond repair.

Fantastic video. I like your clear explanations. You said it at the beginning, getting down to the basics of spark and fuel. The supplies to any gasoline engine, even lawn mowers.

Re: Cost of fuel pump... Within the last couple of years, I replaced the fuel pump in my Chevy Cavalier before a long 4,000 mile cross country trip. The vehicle had around 120k miles and I didn't feel like getting taken on the road for a grand on a job I could do myself at home. But, a check of part suppliers showed the pump is only sold as a whole-fuel-assembly part (pump, sending unit, installation cage, etc.). At a pricey $400 for an OEM ACDelco unit, I passed. After some research on-line, I found an eBay vendor selling just the physical OEM pump for those willing to take the time to rebuild the sending unit -- at a cost of $40. Let me tell you, those sending units take patience and a delicate hand to disassemble. But, the effort was worth it! The new fuel pump allowed the car to bang out the long distance trip without any hiccups. So, the moral of the story? If you're a DIY'er, look at eBay for vendors supplying work-arounds to expensive full-assemblies.

[@ufartface]

good going- mine was $11 lifetime warranty and free shipping of course an access hole makes the job easier

[@Tonetruk]

So, I have had this truck for 16yrs. It is a 2007 Dodge Ram 1500 4.7 liter flex fuel 2WD. It has literally been the best vehicle that I have ever owned, and I would really like to keep her for a couple more years, and then give it to my nephew. Anyways, a couple of weeks ago the RPMs started running pretty high, when I start it up in the morning. Also, I noticed when I come to a complete stop that it feels like the transmission stutters. That said, I drove her pretty hard this past weekend and then ran her through the car wash. So when I was drying her off, I've always been able to take the key out of the ignition and it stays running, but when I go to drive it again, I put it back in, before I take off. So this time when I started driving about 3/4 of the way home it started to really have a tough time shifting out of second gear. I got her home and parked and that's when I noticed that the key was not in the ignition, so I put it back in and shut her down. When I tried starting her in the morning it wouldn't start, all it does is constantly turn over. Funny thing about this is, I got it towed to my mechanic and he was able to get it started by spraying some starting fluid in the throttle body and it started right up and I was able to drive it home. It didn't run great but it ran surprisingly good, but as soon as you turn it off, it won't start again unless I spray the starting fluid in the throttle body again. I know this was long winded, but does anyone have an experience with this problem, or have any idea what this problem could be caused by? The mechanic has a feeling that the TICM has a short and probably needs to be replaced. What say you guys?

[@rael5469]

My wife's car was rear-ended once with minor damage. The body work was completed and we drove it for years after that. Well the fuel pump quit on me one day and I changed it myself. When changing it I noticed that there were anti-slosh baffles inside the tank that were shattered and laying in pieces inside the tank.....I assume from the impact years earlier. The factory must have put anti-slosh baffles for a reason but it didn't seem to affect the smooth running of that car anyway. And we lived on a VERY steep hill.

[@michaelogibowski8370]

Great video. But the bypass relays with the switches Don't come in the $275. Listle kit. It is a Separate kit ,like you showed in your video . The Mac tools kit is $175. Otherwise good info 👌

[@dieseldawg7132]

Yep that relay is built into the mother board and one great way to check it is to check the fuel pump fuse when the pump is actuated bu the scan tool… and finally check at the connectors at the actual fuel pump I don’t a few of these dodge trucks super easy…. I verify ignition with some starting fluid

It's also possible a previous backyard mechanic was lazy and only dropped the tank far enough to squeeze in that first fuel pump, installing it in a compromised condition.

Great video, like your fuse buddy, gettn one. :) Also, great job lettn us know you pulled the fuse before load testing the ground, I was wondering.

Your diagnostic tools kicked Mopar ass. Your info availability was tip top. I just read your entry about the off-road experience and towing. I think somebody either had that apart? Or they beat it trying to get the pump to run when they couldn't hear it. Those things are fragile. I think the filter is contained inside. If they went in after the filter for some reason? I now saw your additional info comment. The tank was clean on your visit. If there really is a plastic piece missing someone may have removed it. Like you showed, it's pretty easy access for a tech. You don't have the service file to look at previous pump inspection, tsb, or recall. At least you're getting paid, and they're getting a Delphi part. If you had to do it, you did it best.
