I was on my way home this morning and my truck died. Almost like a no fuel problem. Had it flatbedded home, and it is getting fuel(pulled line from #1 cylinder, and top of fuel filter) and both had fuel present while trying to start. The only thing that seems strange to me is, after I crank it for any amount of time and turn the key back, the "pump" under the fuel filter seems to run(it goes for ~30 sec. and then shuts off) i am thinking that this is the injection pump, correct me if i am wrong. I never heard this pump run for this amount of time. Any ideas and/or suggestions would help me a ton to get my truck back on the road. Thanks in advance for any replies. BTW its a 99 3500 4X4 cummins.

 

Any trouble codes?Did the service engine light come on?

 

Sounds like what happened to a friend of mine.... The lift pump has gone bad. He had the exact same problem. His truck is a '01 2500 CTD. Frome what I have read it can happen at damn near any time.

 

no cel's at all

 

Mine Did That And It WAs The Injection Pump.. I Have A 00 CTD 4x4 6 Speed

 

stop trying to start the truck, if you keep trying to start it you will kill the VP44.

your lift pump died, get it changed out and things should be ok. hopefully the engine didnt run long without fuel and damage the VP44. . .$$$$$$ to fix that bad boy

 

I dont own a diesel, but a second gen ram. We had a customer come in with running issues and he did change out his lift pump. The new one went, so he went to Chrysler to get a new one, and turns out Chrysler has some problems with the lift pumps in the cummins. So what they did was take a pump like in a gas truck that is mounted in the tank, and do similar, and run the wires from the old lift pump to the new one in hte tank.

I dont know if its your lift pump that is gone, but during that 30 seconds when your pump is cycling, it should put out 1 1/4 to 1 1/2 liters of fuel. And your pressure outta your pump should be around 10 psi, and not go anywhere near 3 psi.

If it is your lift pump, adn you want one to just replace the one you have, Carter still makes them.

Hope this helps you out, and if anyone sees anything that I have messed up, please pipe up. This is info from Cummins and Chrysler.

 

Trevor, I know guys that can pull the fuel pressure down to zero on a fully stock truck. engine still runs fine on the top end with no popping or loss of power.

I'm unsure what mine runs. I do have a feeling I'm drawing it down pretty low since above 2800RPM it feels like the engine is just revving and not going anywhere, but I know, when my LP does die, and I know it will, I'll be tossing in a FASS or Walbro

 

My 3500 has 27,000 on it. It use to start on the first try, now it takes 2 or 3. If I turn the key on for a sec. then try it starts the first time. Do I have a lift pump going bad? Is there a gauge that can be put on it ,to know when you have a problem.
