Ill check it for codes tonight. I think the 5 volts is possibly a reference voltage for the fuel gauge. thanks again.

Alright, here is where i stand. I found the relay, it is good. However at the relay the signal wire to switch the relay over is not getting a ground. I probed the wire and grounded it and the fuel pump kicked right on. So i am assuming that the ecm is not giving it a ground? i dont know where the ecm is located, any one know? Also is there a rollover switch on this thing or security? I am thinking if the rollover switch is bad, or the security is locked out, maybe it tells the ecm not to give the fuel pump a ground, there fore not allowing the fuel pump to run. I really hope it is not a bad computer. thanks everybody.

I am working on a 93 subaru Impreza. There is no fuel pressure. it is a 1.8 with an in tank fuel pump. At the 4 pin connector on the fuel pump there is 5 volts, two grounds, and one that is dead. I jumped from a hot line to the dead line and the fuel pump began to run. I followed the line all the way up through the dash, no breaks. I dont know where the fuel pump relay or the fuel pump fuse are. Could it be a bad relay? nothing in this car is labeled as far as relays and fuses. No numbers, no id plates. Any ideas are much appreciated.
