1991 Chevy Truck 6 cyl Two Wheel Drive Automatic 300000 miles
My engine cranks but will not start, I have no spark. I have a diagnostic program on my computer and I have done every troubleshooting test that pertains to the ignition system. I replaced my Distributor, HEI Module, Pick-Up Coil, Wires, Ignition Coil, Distributor Cap and Rotor, Electronic Spark Control Module, still no spark. I checked all my fuses, all ignition components have good ground, still no spark. All my ignition components have power. Still nothing. Before this happened I had starting problems. It would start cold but after the engine was warm sometimes the starter would not work. I replaced the starter and battery wire and it worked for a while, but then it started happening again. Now it has no spark. I was thinking the two problems were related but I don't no what else to check. I have even swapped out my ECM with one from my other truck that runs and it still won't spark.
have the same problem?
