Chad a few comments that may help:
1) If the wire to the fuel pump shorted to the chassis it is not surprising that
the relay got fried - it would be a direct short of the 12 volts to ground
through the relay.
2) The fuel pump relay is controlled from your ECU. The ECU supplies the ground
connection when it turns ON the pump. It is possible that the relay blow up
affected the ECU but I suspect that you just lost the ground connection from the
ECU to your fuel pump relay - possible the ECU is not grounded very well.
Switching the ECU may have just re-established the ground.
3) It would be interesting to see what happens when you put the original ECU
back in.

Good luck,
Tom
