Ok, Engine starts to fire then quits when key is released.

I will try the suggestions after I buy a new MSD Digital 6 box... A friend fried it by hooking a lead from the pos. side of coil to battery, thinking we could bypass the switch.... Also I am hoping it didn't fry the MSD adjustable timing control also.... Having one of those real bad car experiences right now.

Gosh it's the worst when several things go wrong. We did that on my car before and it worked fine to test it but I just have the stock coil.
