Make sure you give it time to get warm. Did you burp your coolant system?

Ground the sensor throu a test light or something that has resitance. That will tell you if your wiring is good. Once grounded it should raise to the H really fast.

it was the sensor, put a new one in and temp gauge works. I did a full tune up, turns out timing was way off, and now the truck run's great. thanks for your help TylerH
