A couple days ago I swapped out my ruined m20 and dropped in a new one. I didn't open the motor up, just new cooling system and some other maintenance items. When I first started the car up, it ran fine but I turned it off after a few seconds because it was open headers and it was late. After that, it wouldn't start. There is no spark.
I've tried 3 different coils with no change in results and been testing directly from the coil HT lead to eliminate cap and rotor as causes. Coils test positive and receives power. The main relay tested good as well as far as I can tell. Key in the on position ICV hums, everything seems to be getting power. I've tried 2 different ECUs - the one from the car and a known working one pulled from a salvage yard. Ground from oil pan to chassis and valve cover to chassis are new wires and firmly attached.
At this point, I've run out of ideas. Any suggestions would be appreciated in regards to what the issue may be!
