Truck shut off due to no oil pressure about a week ago. Pulled the oil pressure sensor and tried to start, no oil coming out. Took off harmonic balancer and g rotor cover, g rotor was in great shape but keyway slot on balancer was cracked so I replaced that, put everything back together and still no oil pressure. Have also had oil cooler off and replaced o-rings. Anyone have any suggestions??

 

Did you check the front cover? I would bet the front cover is scored.

Not sure what the G rotor your talking about is, I would assume your talking about the oil pump?

 

I removed the front cover, it's not scored.

 

pickup tube in the pan? They have been known to crack ( I read it on the net no personal experience). You could try overfilling the crankcase a couple of quarts to see if you could get above the crack as a diagnosis.

 

I got it, a fuse was blown that goes to the fuel bowl, running like a champ now.
