Based on what I've read has been done - not actually being there - the ECM is floating to the top of the suspect list for me too. (Note the cautious tenor, as I (we all) have been wrong once or twice when it comes to 'lectrik chit!)
I seem to recall there are at least two schematics in the FSM touching on the ECM, DIS, and injectors... I'll keep looking, but my money is on the ECM (at the moment).
Thinking out loud, I know Marc Haibeck provides ECM service (sends them out, if I recall), so if it is the ECM, then there is a solution to that problem.
I tell ya...dealing with GM to get information on repair parts - or even just spec sheets - is a real PIA. I'm just sayin...

Yeah Paul, Johnny said he has already tried (swaping the drivers) so its on to the ECM I guess. Also the QUAD drivers only affect the secondaries and not the primary injectors. Its hard to believe only one injector out of one bank is effected by the ECM although. I know he said the harness was good but maybe there is a micro break somewhere in the harness. Anybody have an ECM to loan him. I dont? GC
I really hate electricial problems
