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

In today's video we take a look at a 2012 Dodge Ram 1500 with a V6 3.7l engine. The owners complaint is that the truck cranks but the engine does not start. Customer states that she had to slam on the brakes abruptly after another driver on the road cut her off. After that the truck lost power, eventually died and would not restart. Follow along as I show you some of my different methods to diagnosing a faulty fuel pump.

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.

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.

[@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.

[@TheCrazy243]

Great video. Also good tip. I almost got burned by few cars. Crank no start conditions are kinda tricky. I guess I’m still learning. Hooking up fuel gauge is a nightmare. I need better tools and also I’m deaf. I Can’t hear fuel prime or click. I can feel only vibration or using test light. Hearing compression sound wise is very challenging 😭. I used scope for extra help. I still check basic.. Spark, fuel, injector pluses ,air ,and timing/compression.Test not guess.

[@SilentWatcher594]

That was some very good, knowledgeable work. And explained well. Nice job.

[@mikechiodetti4482]

Despite what some say here, you performed a VERY GOOD diagnostic test!

[@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 👌👌

[@davidwall6851]

Actually lucky, my 2015 Ram fuel pump relay went out (super common issue) and the fix is usually to replace the TIPM. I built a relay bypass and saved a grip on the repair. Dodge does sell a bypass but it's still expensive but not anywhere near the $1000 new TIPM. Love your in depth video's THX

Great job explaining how you do this and keep up the good work.

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. That's the most likely explanation for the missing plastic and the rods falling apart that makes sense to me. 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.

Nice process Eric! (I know now it wouldn't have worked,. But I would have whacked the bottom of the tank before pulling out test equipment. lol)

[@ADVANCEDLEVELAUTO]

I actually filmed me trying to hit the gas tank with my hand, but I lost the footage somehow. I explained that in my case it was a last resort, because if I tried that first and the pump started working, it would mess with my diagnostic procedure. It's better to test when the fault is occurring, otherwise you could temporarily fix the problem and misdiagnose it as a bad pump when it could be a wiring or connection problem.

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
