If you had the trans with it, it wouldn't have gotten out of second gear.

I sure hope you have the diagnostic link connector hooked up in your truck somewhere....otherwise you are going to have quite a fun time testing all the sensors.
I do have an OBDII port. My check engine light just never came on though. Anyway, a friend of mine gave me a fuel rail with injectors and a regulator. He also gave me a tps sensor to test out on my truck. I replaced all of those and now the truck runs great. So it was either the injectors, regulator, or tps... I'll figure that out later

Thank you so much!
Here is a picture of the truck with the wheels mounted and a fresh wash! I like them a lot.
