I have a 2000 360 ram. I shut my truck off when I got to work , time to go home truck cranks, no start. checked for spark, got spark. ok must be fuel pump. cant hear it run so I check the relay, relay good. I want to make shure power is getting to the pump so I pull the plug off the pump and check all for wires, no power. got any good ideas.

thanks

 

The best way to check the fuel pump is to put a gauge on the fuel rail. If you have good pressure- ~40psi- try resetting the computer. One of my 318 vans is like this. It runs like a top, but every once in a while it will not start. I reset the computer and it fixes it. Not sure whether it's the fuel sync, crank sensor or what.

 

Id follow the wires back and see if there is an open.

 

I don't know what kind of shift he works or if he has any enemies at work, but chances are if the truck got him there the wiring is fine. The fuel pump will only run for a few seconds when you turn the key on to put pressure on the lines, and will not run again until the motor is running. You will need two people to check voltage. One underneath with a meter, and one turning the key off and on. That is unless you make some kind of test harness or have very long arms.

 

check your fuses and relays check them all

 

I am pretty sure it is your relay switch. I just got done replacing mine. Everthing worked but for some reason it would not start. It was the relay switch. Try jumping directly from your starter. Make sure the key is turned to the run postion and jump it by crossing the starter. If it turns over then it is your relay switch. If it doesnt then it is your starter. But hope it is your relay switch just a 10 dollar part at autozone. Quick simple fix it is located in the fuse box. Hope this helps and let us know what happens.
