STILL NO SPARK ON TWO CYLINDERS - ZR-1 Net Registry Forums

SDZR-1 · 09-19-2007

Before I disassembled my top end for a starter and injector replacement I had checked for spark to all cylinders...everything was good. While my plenum was off, I decided to change wires and plugs. After reassembly the car was still running a bit rough, but it was definately a different rough than prior to injector replacement. After checking for spark I determined that cylinders 2 and 5 had no spark to the plug. I figured the only logical explanation for this was that I had a bad coil, so pulled everything apart to install coilpacks when I discovered that 2 and 5 werent even on the same coil and was a little confused....but I put it back together still hoping that it was more than one coil or something of the sort. I was sadly disappointed when it sounded no different than prior to coil replacement and cylinders 2 & 5 still had no spark....I am very very frustrated at this point (and trying to hold my temper back and used it on someone who deserves it...haha) because now I am looking at doing a 3rd plenum pull to figure this all out. The only other idea I have is that the plane that the coils mount to has shorted out....but dammit, I want to be sure this time so was hoping someone had somewhat of a similar experience. So if this is what my problem is....how much more cash am i gonna have to shell out, this is getting rediculous...what a way for a zr-1 to welcome it's new owner.....I guess it ran well for my 1500 mile journey home, so at least I didnt experience these probs on the road.

thanks,
Jarvis
