No spark but 1 spark on "shutdown"

I had the same issue with stock ignition...turned out the wires to the distributor were broken...drove me nuts!!!! All I did was swap carbs out and all the sudden no spark.....make sure your coil wires are on the correct terminal also...

That may be the problem,, one of my "helpers" hooked the coil up backwards and ended up burning out the Procomp coil,, I just replaced it with an Accell competition coil.. Thinking I may have burned up the dizzy module but can't find anyone that tests aftermarket coils.
