After basically finishing my build I’m left with no spark on cylinders 2/3. I switched to a COP set up with new NGK coils as well as using the ARC2 CDI BOX HOWEVER; even after switching back to OEM coils and wires there's still no spark on cylinders 2/3 which helps me say it’s none of the COP set up.
Tested the PTU and replaced it just to make sure both tested good. I replaced the CAS with a new one just to help narrow that away. I visually inspected the ECU everything looks copacetic and good but is there anyway I can test it to verify it’s good? I also plan on doing a continuity test on the harness to make sure nothing broke when I installed the harness. Mind you the car ran before it was parked, is there anything else anyone can think of that I should check or how to chase down my no spark issue?
Also what exactly is the spark path from what I understand it’s power-ecu-ptu-coil and the CAS determines what cylinders get spark
