For the record, my problem ended up being that the wiring plug on the fuel pump was making a bad connection on the top side of the bulkhead. I just popped off the access panel, bent the prongs slightly so they make more contact, and plugged back in. Fixed it! You could always try that. It's free and fast.


Good idea to check the physical connections, mine are making good contact. Theres some other problem going on that I've never heard of.

Ok then lets go with this plan. At the ECU, cut the white/red wire about 6inches from the ECU plug. Test again for a ground when the key is turned on. You are testing the wire that goes to the ECU. Test for ground: Pos lead of meter on battery pos post and neg lead of meter on white/red wire. ***IF that tests good, the ECU is fine. The wire must be shorted to a 12v positive wire. IF you still dont get a ground on that wire then the ecu is shorted internally

Did exactly as mentioned above, with the key off that wire has a reading around 10.7 volts. With the key 'ON FOR 2 SECONDS' I get a reading of 11 volts, not 12. On to the next...

....proceed..... Next take the pos lead of the meter and place it on the white/red wire going to the Relay and place the black lead of the meter on the battery. With the relay removed, you should NOT see voltage. If you see voltage then just stop and post/call me. If no voltage then proceed....

No voltage shown, clearly it shouldn't if the relay is unplugged. On to the next...

Originally posted by Star Turbo TalonTemp Fix that is safe: Take the white/red wire that goes to the relay and splice in some wire and run it into the console someplace to a switch. take the other lead of the switch and ground it. When you turn the switch on the pump will run continuous. This is safe as long as your connections are good and taped up.

Tried this one as well and the pump does not turn on. I'm considering a pump failure perhaps, but I don't have a stock pump to try it out.

Originally posted by Star Turbo Talon***Now go back, if the ECU tested fine above for a ground signal, then run a wire from the ECU to the relay and cut the white/red in between the two (it could be shorted). I should be free tonight give me a ring.

I also tried this one running the wire to try to bypass a short perhaps, but to no avail. The weird thing to me is I'm only getting 11v from the white/red, I can hear the relays click over, but the pump isn't getting juice. I'm fucking stumped on this one. If I can't fix it I'm getting rid of the car plain and simple, I can use the money for a down payment on a house.
