I have not tested the ground at the pump with a multi meter yet and that is one thing I will be doing tomorrow... So far I have tried a new fuel pump, crankshaft sensor, and tested all fuses and relays for positive power, I have power at the pump and power at the crankshaft sensor, The van starts and runs when starter fluid is sprayed into the intake, no codes were pulled by the onboard diagnostics other then battery has been recently disconnected. I have not tested the old pump by connecting it direct to battery yet so that is another step I will take... Its looking like either a bad ground somewhere or possibly both fuel pumps were dead. any other suggestions are welcome, thanks for the help.

 

Is there a fuel pump RELAY that needs to be tested??

 

So this morning I ran wires from the car battery with the pump in hand and got it to spin, so the pump is functional, however the pins that made the pump spin are in opposite corners of the pins that show power at the female harness... So something is telling the fuel pump not to run.... I just dont know what....

 

Reinstalled the fuel tank, put gas in it and swapped the ECM for a reman from autozone and still nothing.... I have eliminated all the usual suspects at this point....

 

You said you had power going to the fuel pump relay. Are you talking about the coil wires or the power contacts? Power to the contacts AND power coming out of the contacts?

 

So did you ever figure out why it's not pumping?
If yes please pass it on to me, I have almost the same problem now.
1997 dodge b2500, water got into the fuel tank, so I removed tank and drained water, but distroyed the pump and retainer ring doing it.
So I hooked it to a inline fuel pump. and it got fuel but would never have spark and/or fire again. ran just fine before the water.
Question does it matter how much fuel is in the tank to make it run,, does it have a shut off so as not to suck up from the bottom so to speak.??
Help please.
