2003 yukon denali oil pressure switch pegged over the 80 psi indicator. Oil qty is good.

Sounds like a bad oil pressure sending unit.

Try unplugging it and see if the gauge drops to zero. If it does than replacing the oil pressure sending unit will most likely fix your problem.

It is not easy to see or get at but you can find it on the back side of the engine on the drivers side, kind of in between the valve cover and the intake plenum

I have a 2004 Yukon Denali. The oil pressure gage decreases when I make a full stop. When the car is running, the oil pressure gage goes up very slowly. I am wondering if anyone has experienced similar...

Your oil pressure will flucuate with the rpm of your engine. It is generally higher also when the engine is cold as the oil is thicker. This is normal as long as your oil pressure stay in the normal operatting range.

Oil gauge on 2003 yukon denali vortec 6000 engine is either all the way to 80 or to 0. can it be the sending unit and where is it located?

on these it is above the oil filter housing underneath. the best way to tell is to have a "wet guage" installed to test what the actuall pressure is. if the oil pressure is to spec then the problem more then likely is the motor in the speedomemeter unit itself. they do have a problem with these little motors. all the guages use the same style motors. cheers

There isn't any fuel getting to my truck and it won't start

No fuel pressure indicates one of three problems. Fuse in fuse box, relay in relay box under the hood or fuel pump located in fuel tank.
