******s13 SR into S14 problem********** - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey guys i'm almost completed with my s13 redtop into my 95 zenki. The car starts up fine and everything works but.... it only runs on cylinders 1 and 2. 3 and 4 have spark and fuel but they aren't firing. I was wondering if anyone else has had the same problems?? We are stumped and possibly think it's the spark timing. Either the plugs are firing too soon or too late..?

HELP please!

check the wiring on the plug sub harness. Sound's like you got things backwards somewhere. Check to see if any of the tops of the coil packs are getting hot, like burning hot. If so you probably did like me and had positive power going into your ground.

alright i'll check the plug sub harness but i don't believe any of the coil packs are getting hot on the top.
