Okay, I did a bit more checking...
1) I checked all the grounds...GTG
2) I checked the power lead to PCM and the accessory wire too. I found that the PCM requires a continual 12V for ACC wire through the cranking cycle. There is no where on the OEM fuse block that can supply 12V from ACC to Cranking and then back.
I managed to connect a switch to 12V. Essentially, I'll flip it on when I want to start the engine.
Is there a wire location and color, that is original to the truck that I can tap into that would provide this signal?
BTW, This thing runs awesome. New cam, DT headers, no cats...you know the deal.
