Oh yah, GM also uses an ignition module on their newish stuff. The one in my 89 1/2 ton quit one night on the way home from hockey. It is a cheap part and I now carry a spare.
This same thing happened to a guy on one of the hockey teams I play against a week later - he was amazed when I pulled out the spare and installed it in his truck and it fired right up.
My guess is that this is your problem.
Oops - I see you changed the module and it still runs, just misses.
I second Ben's comments about a burnt or stuck valve. Have you got spark at all 8 leads? Have you done a compression test? Is there an injector not firing?
