NO oil pressure

Howdy, Ive got a 2001 SD and last Monday I got the scare of my life. The engine has 80k+ miles, I started it and let it run for a couple minutes to clear the windows then as I drove down the street I looked at the dash and the oil pressure gauge was at 0. I listened for a second and eveything sounded normal so I spun a U to go back home and all the sudden the needle pops up to where it should be. It didn't happen again all that week, then this Monday after sitting for a couple days it did it again. The oi pressure gauge stays at 0 until the engine starts to warm then reads normal. Does this sound like a sending unit or gauge problem? Thanks

Have you checked the oil level? What engine?

Symptoms sound like a bad oil pressure sending unit "switch".

Oil level is good, 5.4L, It only seems to do it after sitting for a couple days. It is parked outside and temps have been in the 30s and 40s at night lately.

I would not fool around with this symptom of no oil pres.There have been engines spin bearings on here the last couple months

2) 5.4 and 2)6.8 v-10's

reason= bad oil pumps and overdue oil changes

Get a real oil guage on the truck or take it in and have it chkd out.

Better safe than waiting for something to happen
