These trucks aren't know for high pressure oil system leaks. With the readings that you have you either have a bad hpop or ipr valve. As long as your oil gauge in the dash moves after you crank on it for a while. The only way to tell which it is is to install a known good ipr valve.

Well you have two options. You can remove the pump cover and blow air into the port that is on top of the pump and listen for any leaks if no hissing is heard then replace the pump. Or else you can just replace the high pressure oil pump.

Your oil pressure gauge in the dash comes up when you crank on the truck correct?
