Getting no spark. Engine turns over fine. Changed the ignition module and crank sensor, nothing. Going to change the cam sensor, but doubt that is it. No visible wiring problems. ODB shows the possibilities mentioned above. Any other suggestions?

It has a coil pack. I changed the ignition module and coil packs with known good ones. I also changed the crank sensor and swapped the computer with a 1994 Pontiac Grand Prix and the computer works fine in the Pontiac, but the Chevy still has no spark.
Thanks.

Are you sure you have an injector pulse. If you are missing both then it is a different story.

With missing spark only I worked on a Corsica of the same year and found it was a bad connector to the ignition module. Good luck

I'm getting an injector pulse. I've checked the connector wires, but I'll see if the connectors are bad.
Thanks for your help.

Suggested Repair

With injector pulse present and the coils, ignition module, crank sensor, and computer already swapped, inspect the ignition module connector and its terminals for a poor connection. A bad module connector caused no spark on a same-year Corsica.

Conversation Summary

A 1994 Chevy Corsica cranks but has no spark. The owner replaced the ignition module, coil packs, and crank sensor and swapped in a known-good computer, with no change. Injector pulse is present. The expert advised checking the ignition module connector, which had caused the same no-spark condition on a similar Corsica.
