Ok Last noght is was tinkering with the truck. Getting ready for setting the lifters. It was running fine and i went to give it some gas to warm it up a little faster and BANG! It backfired and no start after that. Now does that sound like an opti problem or maybe an ignition module? It is getting no spark from the coil. Or by some wierd coincidence could the drive pin have sheered off? Any help is appreciated. This is a 1993 LT1 in a 1996 S-10. Thanks in advance-Joe

I am having the coil and IGN module tested today by my buddy. Hopefully it was one of those!!
