1990 Chevrolet Corsica Repair Question
1990 Chevy Corsica Car turns over but won't start
1990 Chevy Corsica 4 cyl Two Wheel Drive Automatic 100000 miles
My 1990 Chevy Corsica won't start, I have replaced the plugs and wires, coil packs, fuel filter, fuel pump, taken off catayst converter, and when I try to start it, it backfires through the throttle body, starts for a minute then shuts off. And then it will crank but not start. What could be wrong? I would appreciate your advise. D Youngs, Florida

Crank and no start do below to determine what's causing it
Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
