Changed the fuel filter on my buddys 06 lbz duramax and cant get it to prime. Never had this happen before. When pumping it wont build up pressure and just barely squirts out a bit of diesel. I tried closing the screw to try to build up some pressure and it still wont. Checked all the o rings. But the WIF sensor wires had been torn right out of the sensor by previous owner(he just bought the truck), and the sensor is pretty rugged looking. Dont know if that has anything to do with it.

Yea i looked it over good and couldnt see a crack and i didnt think the wires being pulled out of it would prevent it from priming

what is there to check on it?

is there an o ring on that too?

All right thanks, but the wires being pulled out of the sensor has nothing to do with priming it right?

yea checked all that, but it feels like the two o-rings inside the pump button arent sealing up too well so maybe thats it. He just bought the truck two days ago, its got a 30 day warranty so there coming to pick it up today. I put the old fuel filter back on and let them deal with it. Thanks for the tips though
