Then, hard wired the pump, and the intake air temps PEGGED at ~120F. They would fluctuate a bit, up and down maybe 3 degrees depending on how hard I got on it.

Then, I did another test, and wired pins 2 and 7 on the N65 block together. The pump comes on like a champ, every time the key is in the on position. This leads me to believe it's definitely the relay. I am happy, now I just need to figure out what to replace. It "seems" like I might have to replace that whole part the the N65 block plugs into. Not sure about that yet...
With my limited knowledge of sparky stuff I wonder if bypassing the solenoid proves anything, I think it is possible that the signal that operates the solenoid is to blame.
