was it no spark at all, or just on one or more cylinders?

Thats a great question and I think I know where you are going with it. I noticed the individual coils last night when I pulled the head off of it. I guess if there is no spark in 1 cylinder, one of those coils could be the culprit!?! Alternatively, if there is no spark at all there may be another componant that is bad. I guess I assumed that there was no spark since it didn't act like it wanted to fire at all. I only tested one cylinder for spark though. I guess I need to dive into that a little further. Thanks so much for the reply....

Do you guys have a favorite place to buy parts for these things???

if its only one cyinder with no spark, pull the coil an clean the graound strap on the coil(better do it with all of them), if it has no spark, disconect the main engine wire harness, tehm jump the starter selenoid(red to yellow/red) adn see if it sparks, if it does then, you have a harnes or key switch issue

I was going to suggest you decarb the head and cylinder tops while you have it apart but that looks clean enough to leave alone. You could now spray some PB blaster directly on the rings though just to loosen them up. I would get the headgaskets and button her back up and recheck compression. I bet you are going to be pleasantly surprised. Get her healthy on all six and I can find your lost spark.

ok, got the compression problem fixed with a new set of head gaskets. I installed new thermostats and spark plugs as well. I went ahead and pulled each one of the coils loose and cleaned the contacts on them. Alas, it appears as though I STILL have no spark at all.

Starter cranks like crazy and the TNT works well but no spark. What can I look for to find a way to fix the spark issue?
