Computer problem
1989 GMC C1500 V8 Two Wheel Drive Automatic

I've replaced plugs,wires,cap,button,coil,pick-up coil,and module. It turns over but won't start. Could it be one of the computers that controls fuel or firing.

Welcome to the forum, did you visually check for spark at the plugs, engine cranking? If you have TBI fuel injection, can you see injector spray pattern, engine cranking? also, use a gage and check fuel pressure? Any trouble codes?
