bad coil pack. would be my first suspicion. go to JY, replace all three packs with ignition plate, test, problem fixed. :)

While the typical problem would be looked at as a possible bad coil pack, check the #6 plug. We only have 3 coils and therefore (I forget what Don said it was called) both plugs fire at the same time. One spark is wasted, one is used.
Therefore check #6 and the coil tower on #3, it's also possible the tower is broken or cracked. It may also be your ignition control module. |

For those of us who aren't so savvy.. what is JY ? Thanks. Sam B. |
JY= junkyard or auto wrecker, aka cheap parts.

no spark on number 3 plug
thanks for the info. i have a 96 bonny se can i take the parts off the 96 se for my97 ssei will it work.

Chuckiec4 has a 96 bonne SE at home also. I looked up the part numbers and the coil packs are a different number between the 97SSEi and the 96SE ignition coil packs, but, would he be able to use a pack from the 96 to see if the pack on the 97 is bad? I know it's a different part number, but if it fits, would it work?
Thanks. Sam B. |
The SSEi packs throw a hotter spark. For testing, it will be fine. If that doesn't work out, pull all three coil packs and swap the ICM located underneath them.

Both the ICM & coils would have to be good if #6 is firing. You might want to double check #3 & #6. How are you checking for spark?

ChuckiC4 took 1 coil pack off the '96 SE and replaced the #3 / #6 coil pack on the '97 SSEi, and the check engine light went off, and the car runs good again. He is planning to replace all 3 coil packs, and probably the ICM as well. Do you guys suggest a specific brand? or should we get OEM? Where do you guys buy your coils? Is there a good source for good prices on good parts? Thanks for the advice, and for helping us get this Bonne up and running again. I can't tell you what a relief it is to see him happy again.
