No spark... changed wiring harnesses, etc.
 

so a 86 NA shell was passed on from one friend to another friend of mine. the car ran great, but when the engine and driveline was removed and relpaced, theres no spark. weve replaced the indash harness, power harness and engine harness. also all the fuses were replaced. no spark. Any ideas?????

does the cas signal make it to the ecu? ecu getting power? coils getting power?

I need to get in the parts selling business, I can see that clearly now. More profit there.

Throw more parts at the problem.

Check your main relay.
