Hello. I have a denali and my oil pressure when
starts it goes to half then drops to zero while
warming up, and will stay at 0 until i press on the
gas pedal the. Goes to normal and then goes back
to zero when i take my foot of the gas. As i drive
and gets warmer it goes back to zero at a light
when i stop. Can you guys help me with this issue?

Maybe just teh oil pressure sediswitch is bad.Locate it and replace it. They are very cheap and usually easy to install.Try U-Tube for a how to video for your Vehicle and engine.. If the engine is making noise-ticking clacking,when it says zero you really have no oil pressure.Get the motor flushed-maybe even twice. Use a slightly heavier grade of oil. If that doesnt help you might have to drop the oil pan and see if the oil pump screen is clogged,or pick up tube is no good. After that its oil pump or worse. You didnt say how many miles you have.
Sorry for the typo should read "the oil pressure sending switch"
SOUNDS LIKE OIL PUMP WORN TRY CHANGING THE OIL AND OIL FILTER,, SEE IF THAT HELPS.
just to be safe you should have a master guage installed to into the system and check oil pressure . I am sure you can rent one or have a shop do it cheap , to give you piece of mind and make an informed decision.
Hi I have a 2007 Denali I was driving and my oil pressure light came on and said I was losing pressure. I turned it off then turned it back on started driving and now it's not showing anything. Got home check the oil everything seems good any ideas what happened or why it was showing I was losing pressure.
