So starting out 95 sunfire 2.2 ohv. No spark. Check crank sensor and the end was dented in. Replaced still no spark. Icm is getting 12 Volts and ground . Other 2 wires in the icm are coil triggers and I know of no way to test them. Have tested with icm unmointed from block but grounded to block no spark on any cyl. The first time I tried to fire the motor after building it I forgot to hook up the engine to frame ground. Shorted something?? Hooked up now And cranks all day long but no spark. Icm tested ok on icm tester. Just short of having someone come over with a oscilloscope to measure 7x signal I am out of ideas. If my megasquirt is hooked up to fuel and wires are cut to the injector drivers off the stock PCM will that cause a problem??

Thanks for all the help
