You could just have a bad oil sending unit.You will have to have the oil pressure tested.The other thing is there is a recall for the instrument gauges sticking.This would be a free repair if you are under 70k miles and 7yrs.If your over then up to 80k miles the dealership will furnish the part but you have to pay for the labor.But I would get the oil pressure checked first.The recall number is 07187C.Good luck.

It could be the sensor that screws into the back of the intake manifold next to the distributor. It is an electric sensor so it could also be the connection where the harness plugs onto it. Check to make sure nobody unplugged or loosened the wires during a tuneup. Those are the inexpensive things to check. Since you said the gauge is stuck on 80 I don't think it is the gauge itself since the tend to go to 0. If it is the gauge the whole gauge cluster panel will need to be changed out. You may have to take it to a shop to determine if the gauge cluster is the cause. Good luck.

1996 GMC Jimmy. I had the oil pressure sending unit replaced by a mechanic. The oil pressure gauge is still pinned on max. Lost now.

have the oil pressure checked with a mechanical gauge to determine the exact pressure reading. It may be a stuck pressure relief valve in the pump (gauge correct) or a faulty gauge ( sender unit correct)

The oil pressure gauge is going directly from soon as you crank up the vehicle....Its running fine, no lights have come on, running smooth like normal, its just that the gauge in the dashboard...

It sounds like there is a problem with the oil pressure sending circuit. The oil pressure sender changes voltage according to the differences in oil pressure. If it is pegged all the way to the max, there may be a short (or open, depending on the way the circuit is designed). I would take it to a shop and have the oil pressure tested with a mechanical gauge first, just to be sure there isn't a problem with the relief valve on the oil pump. But if the oil pressure gauge isn't working properly, you won't know if there really is a problem with the oil pressure, and that could be catastrophic to the engine.

Oil gaug

GM Had A Recall Issue W/Dashboard Cluster, Speedometer ... Etc ... I Would Goto Your Dealer And Say That. But If You Don't Have A Warrenty Or Such, If Your Familier W/Your Truck And We All Are .... You Know That That's Just HopeFully A FAULTY Dummy Gauge As They Refferred To Them In The Ole Day... But If You Reg Change Your Oli @ Every 3000-5000 Miles As Suggested, You Know Exactl;y Where Your Truck Is, I WAs Recommended The Same Thing, But My Fix Was To Just Install A Aftermarket Oil Pressure Gauge, Which they Are More In -expensive Then This New Gauge For You Dashboard Oil Light.... Unfortunately But They Are Twice As Reliable, Hope Any Of This Was Of Some Help, James W
