s13 Posted September 30, 2006 Report Share Posted September 30, 2006 Alright. It is a 1990 eagle talon tsi fwd. This black-blue wire runs from the MPI relay into the the computer. If I ground the wire to an alternitive ground the car will start. If I leave this alternitive ground on it turns the relay over and runs the battery dead. If I leave it how it should be the ecu will not ground itself and the car will not start. My guess is the transitor in the ecu is bad. So does anyone have a spare 1990 turbo ecu I can borrow to test before buying a new one. Or any other guesses on what might be wrong? Also the MPI relay was tested and is fine.
