Well, guys, I know you were racking your brains to help me get Heavy running again, & I got her back today. The BIG problem that was causing the no-start was the IDM itself. They had hooked up a 'test IDM' to the truck & it ran, but was skipping like crazy. After some testing, they found that cylinders #2 & #7 were weak. The problem was coming from the IDM harnesses(like you all had mentioned!). They installed the clips that someone else had mentioned on that thread, & it ran like a champ! Tony, as far as that hard shifting I had PM'd you about: I think this whole IDM problem was the cause. I haven't given it a good test yet, but when I drove it back from Ford, there was no hard or early shifting. I'll PM you info if I do end up having a problem, but I think the injectors being weak was possibly the problem. Thanks to all of you for going through the trouble & giving me a hand!:yourock:
