Thread: Grand Prix stalls and no start.

I was just sitting at a light and my gp stalled out and when I attempted to restart it it would start for a brief second then die out. When I pushed it out of the road and popped the hood I noticed the bottom coil pack was cracked in half. So my question is it just the coil pack or could it also be the ICM. I would assume that a v6 motor would still start and run even though it would run terrible on only 4 cylinders

If the coil cracked, then it's possible that the ICM got taken out as well. Went through this on my 00 GT. And yes, theoretically it would run on 4 cyl.

Replace the known issue with the coil and see if you get lucky.

Update: replaced coil pack no difference, replaced ICM and runs like new! Thanks for the help!
