Did a little more trouble shooting, on starter solenoid I am getting power to post with heavy wire but not to the other large post when I try to start. Just replaced solenoid and it still does the same thing. Jumped across post with screw driver and engine turns over. Tried moving from park to neutral back to park and even wiggled gear lever while trying to start, nothing. Looked all around engine for loose wires and found none.

***Note: Last time truck was running the idle pulley broke and got my fan. While replacing fan I changed the GPR which was bad, and installed an Issopro Trans. Temp sensor. Gauge was installed a few months ago.
