I feel your pain, it took me 3 weeks of more then just sundays to get mine going. I rewired and reprogrammed with EFI Live myself. Went to start it and had no injector pulse and no spark. I rechecked every pin on the ECM and traced a lot of the wiring... LONG story short I reflashed it with a different vin and it started right up........ But man, all the hate was gone when the sound of open headers scares the crap out of you.......
