I have a 1997 gmc sierra 4.3l i just put a new fuel pump in it, and there is tons of pressure to the intake and i have spark but it will not start so i checked my fuses and they are good so im not sure if its the injectors or what it is
I have 1993 gmc 4.3 vortec v6 turns over but want start. replaced fuel pump, fuel pump regulator ,ecm, tps, coil
Do not turn the distributer if it was runing good before its not the timing check for spark in the injectors unplug one you must buy or rent one from auto zone
Sometimes there is a reset button or you could mess with the distributer cap turn just alittle and see
