I can feel your pain. Don't give up on it. Do you have the factory service manual on the truck that the motor came from. I'll look and see if I have it and I'd so I could drop it o. A thumb drive and mail it to you. Its a big help to know the color codes for the wireing. Also do you have all the needed parts and pieces? Do you have the PCM and the gas peddle? There could be other things as well. Or have you considered going with aftermarket EFI? I'm planning on setting mine up on megasquirt. And it is posing it's own challenges. I know it's difficult but don't give up on her just yet. I eat, sleep, and breath the modern Hemi. We can get it up and going. The only problem is my schedule is really full. But I'll help you as I can.
