HELP No Spark
Gonna throw this in general tech as well. Did an HSR swap on an 86 camaro. When parked it ran. Had to swap to an external coil distributor. Has no spark with new instake now.
12 volts to ignition coil key on.
12 volts to distributor key on.
All ground wire on harness connected to cylinder heads
Tested the ppl/wht wire to ECM which is a pulse reference ground, test light flashes while cranking.
Replaced ECM.
Have tried 2 ignition coils, and just put in a 2nd new distributor, still no spark.
Volt meter hooked up the ignition coil secondary terminal (where spark plug wire connects) and have battery voltage while cranking.
I have no idea what to do.
