You can hope so. If you install a new sending unit, you will find out if it is something worse. Loss of oil pressure can indicate low oil level, damaged oil pump, a broken sending unit wire, a defective gage or a worn-out engine.

You need to get a manual oil pressure gauge that reads LBS. per squire inch so you can read what the oil pressure is for sure.

I would give you the oil pressure SPECS. and tell you where the sending unit is, but you did not say what year are engine size and what it is in.

Where is the oil pressure sending switch on a 1989 GMC Sierra not the fuel pump relay?
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.
