First thanks to everyone who looked at and commented with all the helpful suggestions in the forum and in PMs.
Ok, I found the problem....Upon disassembly on a controlled Electro Static Discharge (ESD) free workstation I did a thorough inspection of the pcm and found a main board input lead on the green connector (lower) was pushed in enough to back up against one of the blue connector input connector leads causing a short resulting in the P0200 Injector driver failure hard code. Fortuneatly signature analysis with the Huntron Tracker showed no permanant dammage to any of the onboard components and the repair was made to the pcm's main input connector. Tonight I sucessfully reinstalled and put the new pcm through serval on-off drive cycles in the truck with the original Pro Tuner tune with no problems. Lesson learned here on our end...before you launch into low earth orbit on a galatic troubleshooting scheme, carefully inspect the unit in an approved ESD free station for the most or not so obvious of malfunctions, in this case a pushed pin. Next question how many other pcms have been thrown in the dumper because of the pushed pin senario?-just something to think about folks.
