Thanks for the input, I apologize I have been slow in responding. But to answer a few posts....
First, I will try the heat sink trick and see if it works
I purchased the IP and injectors from Pensacola Diesel. Unfortunately, I did not know about their reputation prior to the purchase as this my first IDI. I know it's under warranty but I sure don't want to have to do the work all over again. But the heat sink will reveal the truth.
@IDIBRONCO, your timing suggestion might not be to crazy. I had to advance the timing quite a bit as it ran really rough and smoked like crazy when it fired up after the install. If the heat sink doesn't reveal a problem I will go to timing.
@hacked89, great question. I replaced the entire system because it was all original to the truck. Dinah, [that's what I named the truck], came home on a wrecker back in February with total IP failure. So I replaced every component and when I removed the old stuff it was all dated 12/85, indicating the FI, IP, and return system were original to my 86!
While I was under the hood, I replaced the entire cooling system, all the belt driven components, all new belts and hoses, and did some trans maintenance. I have rebuilding the and converting the A/C system, new brakes, new wiper motor, and new radio on my short list of upcoming repairs and improvements.
I will keep y'all posted on the heat sink results
