View Full Version : S13 SR spark problems...

I just finished my swap and got my PFC in working order. It cranked fine and fired right up... Then I noticed it was having trouble idling and sounded like it was running on 3 cylinders. I checked for spark and I'm getting spark on #1-#3 but no spark on #4. I pulled the #4 coil pack off and plugged it into the #1 coil pack plug and got spark just fine.

Now the question is.... My coil pack sub harness is a bit hacked up looking.. well it is hacked up. It definitely does not look factory at all and has a bunch of electrical tape in different places. I've already checked the ignitor chip and it has power. Is there any schematic for the coil pack harness to see which wires are supposed to be routed? Also, is there anyone selling a non-molested coil pack harness :confused:

Thanks,

-Trevor

Sounds like the ignition harness is messed up since the coil pack itself is fine. Check the harness for shorts with a multimeter.

try testing a different spark plug on that cylinder
