not sure that it would say the light would indicate too much pressure, but usually the light will come on when there is not enough pressure (too little oil). inversely, the light may come on if there is too much oil.
where is the oil pump on a 1998 gmc jimmy in the oil pan.
where is the oil sensor on a 97 gmc jimmy
What type of oil for a 2000 GMC Jimmy
The oil pressure is located on the side of the engine block. The switch has a black plug with three wires connected to it.
Where is the oil filter on a 1999 gmc jimmy
The oil pressure sending unit on a 2005 GMC Sierra
oil leak
on the bottom of the engine.
I know in my '97 Gmc Jimmy the oil sending unit was bad when I had the same problem holding oil pressure. When I'd start my truck it had almost 40 lbs of pressure that would slowly fall off to nil unless you accelerated. Then the pressure would rise somewhat.
The lack of oil?!?
4.2 quarts of oil
Either it went under hard accelleration all of the time or the oil pump cavitated, leading to no oil pressure
