Ground for fuel pump under driver seat been disturbed or loose?
colt45:
The grounds to the driver seat had been clearly cut and soldered and then over heated. Found a circuit trace in the main relay blown. I ran new larger gauge wire for the fuel pump grounds and soldered in a jumper over the blown out trace in the main relay. Only 1 relay pulls in in the main relay. The I'm thinking the relay soldered to the board may be dead also.

talking about in ecu?
colt45:
The main relay has two relays internal to it. Using the manual amd a multimeter, I proved the main relay is fine. Fuse 44 in the engine bay fuse box was missing. Replaced it and it popped when I tried it again. Now I'm down to troubleshooting via process of elimination to find the short. I'll let you know how it goes.

if you have a working car around id try a different main relay, i've had issues like you are having and rather than chase a ghost its good to know its a working part you can test in a different car. i also wired the pump directly and what not but never could trust that relay.
