When you "jumped" the relay and it worked, how did you jump it? Did you go arouund the relay, or did you turn on the relay by suppling ground to the relay coil? I would also verify the ground signal to the fuel pump relay that comes from the ECU. Remember, when you turn the key to on, the ground signal from the ECU only lasts a few seconds to prime the pump, then it shuts down.


I pulled out the relay and ran a wire from terminals 2 and 8 off the relay to the battery. Based off the relay inspection picture in the posts above.

Terry has been giving me the same advice and this is what I've came up with so far.

AFAIK on a 97, the white wire/red stripe PIN 74 on the ecu plug harness is the ground signal wire to the fuel pump. With the relay plugged in, I put the + off my multimeter at battery, - to fp ground signal wire(white wire/red stripe) I get 12v on the meter with the key turned off.

With the relay unplugged, using the same connections as above I get no reading on the meter with the key off, or when it is switched to ON.

I don't know exactly what I'm doing, or where the grounds are that I need to be testings. It's quite confusing and I've been learning as I go trying to solve this problem, which is basically a disaster.
