Okay,I just switched pcm's and am using another.But I wanted to try it in the vehicle since it has the proper ign/batt power.
And sure enough mark it finally worked.
What gets me is I tried to change it on the vehicle last night pretty sure and got nada,must be remembering incorrectly.
I will rewire my bench harness,it has an off/on switch and that is it. I will just swap the switch to the ign circuits and wire the 12v direct.
Never had this issue,but I also generally only do VATS stuff on the bench usually and like mentioned before don't mess with ViN much. (I stay away from mailorder work,if I possibly screw something up I like to put hands on tools to verify/diag in person).


Thanks for the tip.
