Hi, guys. I just swapped out my coil loom yesterday for a wiring specialties harness. I went for a quick run up and down the road and all was well. I went out this morning to swap out my mines ecu for a stock one I have. Started the car and cyliner 1 has no spark. I swapped the coils around and still cyl 1 has no spark with any coil. I visually inspected the ecu connector and immediate wires and they look fine. I get 12v to the coil when key is in on. I've since swapped back to the mines ecu and the problem persists. Really wish I would have started it before I swapped the ecu. Im thinking the ignitor is ******, anyone care to chime in?

Yeah. Back pedal more. (check harness connections INCLUDING the ground wire to the ignitor). Use the stock harness and see if that fixes the issue.

I had something like this happen to me last year. Check pins on coil aren't bent. Also wires on the ecu plug from harness. I had one that was just a little loose.

Ecu connector!, it was flexing when being tightened, thanks for the help guys
