Asked by Sep 22, 2011 at 02:43 PM about the 1994 Toyota Pickup 2 Dr DX 4WD Standard Cab SB

Question type: Maintenance & Repair

HAD MOTOR CHANGED/REBUILT , SINCE THEN, ECM KEEPS GOING OUT AND HAS FILLED THE CYLINDERS UP WITH GAS THREE TIMES. WHAT IS WRONG?

1 Answer

you have a pinched wire to your injectors somewhere. your injectors have constant power and ground trigger from your ecm to get pulsation. turn your key on and with a test light check your ground wire to your injectors. should not light up unless your cranking, even then it should pulsate not stay lit. hope that helps good luck
