Doug,
It has been = years since my plane moved to another owner, but he had a = similar problem after removal and reinstall of the engine. The = problem was the very short ground from the coils on the wall to = the engine got removed. recheck your grounding DIRECT to = engine.

I also = remember that the EC-2 had  a mode that would fire the plugs = repeatedly (similar to the function for the injectors) have you tried = that? If they fire with that function and not when cranking, then the = problem would lie with the trigger signal
