Did the car start and stay running with the relay jumpers? What I am saying and tried searching through the slectrical drawings but I'm heading south tomorrow to San Diego down the 101 but a storm is starting up in Calgary. Oh ya the green relay is energized by several events starting the fuel rail is pressured then the relay turns off waiting for a run signal once received from the tach the pump remains on until a roll over or normal shut down.
