Thoughts from a knuckle dragger: Checking for voltage to the coils may help trouble shoot. Otherwise if you swapped plugs, leads, coils you may be right with the ecm. Sounds dumb but have you checked your battery, it doesn't take much loss to cause trouble. Just for gee-whiz'z from an issue I had with a pulse generator I found I needed a peak voltage adapter to check peak voltage, as an alternative you could measure the output voltage from the pulse generator with a multimeter then divide that number by .707
