Anyone resolve this before?

3 weeks ago I had a oil pressure sensor error... Long story short I was 4 quarts low on oil. I brushed it off and placed blame on the dealership. Fast Forward three weeks and I'm driving to work with zero oil pressure on the gauge. I thought it was the gauge since I got no movement with the key in acc power. I decided to check the dipstick even tho I knew it was just filled less than a month ago... Low and behold the freaking oil is dry again and not even registering on the dipstick. I'm lost because I've checked for leaks and haven't found anything... PLS HELP.

Its burning it... and its really common. Welcome to the world of active fuel management. Your oil control rings on the cylinders that shut off are a gummed up mess and don't do anything anymore. You can either overhaul it or swap in another engine.... and if you do either delete the AFM lifters, solenoids and add a non AFM timing cover and lifter valley cover. Then enjoy a normal running truck.

The fact you have been running it without pressure..... well sorry the engine is garbage no matter how you paint it.

***Update*** put 2 quarts in and the oil pressure gauge is still at zero. I got a high voltage error code to the oil pressure sensor.

Update- I ended up removing the oil pressure switch and replacing it with a manual oil pressure gauge. I needed to know that the engine still had oil pressure because the dash gauge was on zero. So that eliminates the worst fear for me which was a internal issue or oil pump.

Next- testing the oil pressure switch with I jumper box and a test light.

Then if that checks out... Dash gauge, and wiring

SORRY not overhauling or replacing engine yet folks!!!
