The oil pressure may vary depend on mileage. However, typically on a 1988 GM engine should be around 14.25 ohms or more.
this is normal, when the car is cold or off. the oil sinks down in to the oil pan.,. If this is a GM engine you may be using an aftermarket oil filter that allows oil to drain back this is not a good thing and can cause engine damage. GM has a TSB on this very problem.
the oil pressure sender on a 2000 gmc is in the back of the eng. top side
It is built into the oil pump/ Part of the oil pump.

You may need to change your oil, it may be normal for this vehicle to be in the red at an idle. The engine is not under any pressure. also a very common fault for gm v6 engines loss of oil pressure at idle is often caused by worn out main bearings. i have salvaged many engines by changing them.
