So recently I had to replace my lift pump due to it failing. As soon as I replaced the pump and drove down the road the truck started skipping and bucking and lost throttle. I read on another forum on how to test the optic sensor by unplugging it and starting the truck. The truck started normal...
1995 c3500 having some issues with the optic sensor on it I purchased one from a place called Johnathan tacker store and I'm pretty sure I got scammed.
