Question about 1992 Pontiac Grand Prix
It will not blow when ECM is disconnected, cause there is no power to the injectors when you disconnect the ECM. When you turn ignition on check for fuel pressure at fuel rail. Release pressure at nipple on fuel rail. If no pressure exists puel pump is shot. If there is pressure your fuel filter might be plugged.
