Oil Psi ? Help A Brother Out:)

[cumminsrocks]

I Have been working on a 04 Excursion. Did studs,full delete,sct tuner ect. ran great for 30min, and then threw a code for low psi all injectors. Dont remember code sorry, i wasnt driving it at the time. Then later on that day, the guy says it now has check gauge and shows no oil psi but runs fine. I did some digging, and I know to check sensor needs 7psi ect for the switch, but the gut feeling i have is the plug in hpop maybe?
If anyone with some actual knowlege of oil psi system could give me a lil tip or a direction, i would appreciate it. I am thinking about getting the updated stc fitting and gasket kit for the hpop and go in there and do that and check things. Sound like the right thing to do?? Thanks in advance.

this morning it had oil psi for 15sec or so then the gauge went to 0. Still runs strong, threw no other codes.

the truck cannot run without oil pressure, change the oil pressure sensor on the oil filter housing. I bet it is cracked and has oil in the sensor.
