Default Ignitors???

I check coils for spark. there wasnt one. not one coil sparked. I guess my question is, do the trailing coils piggy back off the leading coils? Is it possible that the leading ones are just bad? or is it something completely different? If anyone has any ideas let me know please...

Check if there is power going to the coils on the harness and go from there.

The leading and trailing coils are entirely seperate, one could fail and the other would continue working.

Each has it's own ignitor in the base of the coil pack.
Leadings has one.
Trailings has one.

Do you know what the spark looks like normally?
Usually, they look pretty damn weak.
If you'd seen a spark thrown by a CDI box, you'll understand.

do you have a "harbor frieght" or similiar store around? What you need are one of those cheapy spark testers that are essentially a light bulb in between a spark plug wire.
