hey everyone, just got my swap finished and after 2 days of driving around my car started to sputter and miss. Idle is fine, Vacuum is fine...checked all 4 coilpacks and they spark fine on all the other cylinders. I tested all of the spark plugs and they fire. I also took the coilpack harness off and tested it...fine also...
I don't think it would be a bad ignitor because all the other cylinders have spark. Could it just be a shorted wire in the wiring harness or a wire that grounded itself out? Next thing I'll check is if my ECU's plug isn't fully connected but the car's sleeping at a friends house in san jose...didn't really want to drive 35 miles on 3 cylinders...
Fuel and compression are both fine so this is def. an electrical issue....I just hate this wild goose chase bull**** right now! I want to drive my damn sr!!
Help would be greatly appreciated! thanks in advance!
No.2 Cyl has no spark - already checked the obvious

Re: (Nismo_Freak)
Does anyone know what my ignitor should be reading on a multimeter? And can anyone refer me to a good place to pick an ignitor up in case it has failed?

Re: (Nismo_Freak)
what section of the fsm would the reading be in?
Wait, can you use the 300zx and q45 ignitors with the sr20?

Re: (Deadrodent)
alright guys, fixed the problem. The ecu plug is cracked...i just unbolted it and plugged it back in and the engine runs fine now. but i really don't like the fact that i have a cracked ecu plug. i don't want to have to keep unplugging and plugging it if the problem comes back. what's the best way to fix this without getting a new wiring harness? i guess just cutting the wires and soldering on a new plug?

Re: (Deadrodent)
I'd say electric tape it around the harness a few times with it plugged in. That should keep it together. I wouldn't tape it to the ecu though.
