got it... so if the ecu is not grounding the fuel pump correctly i would not get any fuel pump if i bridge the power relay.�so if all grounds are good on ecu which they are this would indicate a bad ecu then?sorry for the confusion.jess

Jesse, as Scott (?) and I have said, the ECU drives the fuel pump relay.� It does not come direct from the ECU power relay.

This has to be so that the ECU can shut down the fuel pump in the event of an accident.
