The oil pressure sending unit on a 2005 GMC Sierra
The oil pressure sending unit on a 1989 GMC Sierra is located slightly above the oil filter. You will need a flashlight to find it. It may be hard to recognize it because it should have a heat shield around it as well. Look for its wire coming down from the engine compartment and follow it to the oil pressure sending unit. Drain your engine oil and remove the oil filter to make changing the oil pressure sending unit easier.

The temperature gauge will not work on a 1984 GMC Sierra truck if the sending unit is defective or the wiring has come loose. It is also possible for the gauge itself to fail, but this is less common.
It is right behind the distributor.
If you are have fuel gauge problems I would suspect the sending unit in the fuel tank to be at fault. Rarely the gauge is the problem.
The oil pressure sender or switch is located at the rear of the engine, behind the distributor.
