So, here's an update. 1st Mechanic diagnosed bad HPOP and failed injectors. Second mechanic diagnosed bad HPOP but thought the injectors were ok. Bought a new HPOP from Diesel Power Products and 2nd mechanic installed it, still no start. Bought 8 new injectors and had them installed, still no start. Pulled out the IDM and installed it in our '97 to see if it would run, works fine in the '97. Mechanic says he tested the harness everywhere he could. At this point, I think we've wasted a ****load of money on a wild goose chase. What do you guys think? PCM? Harness? I'm completely out of ideas here and clearly, the 2 mechanics we hired are too.

Have you looked at the wiring harness on the outside of the drivers side valve cover...towards the wheel well...as it comes out of the 42 pin connector above the valve cover? The harness can rub through the wiring on the valve cover.
Holly molly those mechanics are wasting alot of your money. I recently had a bad IDM and a simple buzz test would tell you that either it's bad, or verify which injector might be bad so you don't have to replace all of them.

SOOO... just a quick update:
Pulled the PCM/ECU and sent it to Ford to get tested. Apparently, its junk and that was the problem all along. I'll update again when we put the new PCM in but I think this thread will serve as yet another cautionary tale about proper diagnosis before parts changing.
