It depends if you are getting oil to engine or not. When you start motor do you hear a clattering on the top end of motor. If so, then you indeed probabably are not getting oil to engine. Easy way to tell also is pull off vale cover and see if you are getting oil to top end of motor. believe me, you will know if your are pumping oil, it will be everywhere. If you are getting oil then probably oil pressure sending unit is bad. If not, then oil pump is bad.
There is more than one sending unit, such as engine oil pressure sending unit, engine temperature sending unit and fuel gauge sending unit to name a few. Need more info.
You need to replace the oil sending unit.
Remove the oil pressure sending unit retaining ring. Remove the wiring harness from the sending unit. Poll the sending unit out of the engine.
Why in the world would you want to do this? If the sending unit is defective then replace it. If the light is on you either have low oil pressure of the sending unit is bad. Low oil pressure will ruin your engine.
This is only going to answer 1/2 of your question but the oil pressure sending unit is on the drivers side of the engine , below the power steering pump
If that is all that is wrong and you know 100% that the sending unit is bad, then my advice is to replace it. It is a cheap fix and if you do not replace it you have no idea what your actual oil pressure is. This could cause you to drive around with no oil pressure which would destroy your engine. Just replace it and then you can rest easy.
Probably you need to replace the oil pressure sending unit. It is located on the engine down close to the oil pan. If the sending unit is leaking oil then replace it by all means. Doubtful that the oil pump is defective.
There are several sending units, engine temp, oil pressure, fuel level to name a few. We need to know which one and also the year, make and model vehicle.

The oil pressure sending unit on a 302 ford is located on the block of the engine. It screws into the block and the sending unit goes on the end. The oil pressure sending unit on a 302 Ford is slightly above and to the left of the oil filter. I find it is easier to replace with the oil filter out.
HELLO , I THINK POSSIBLY THE OIL PUMP IS GOING BAD, SO I WOULD REPLACE PLACE IT AND WITH A NEW STRAINER AND GASKET. EVEN REPLACE THE OIL PRESSURE SWITCH OR SENDING UNIT ITS THE SAME THING!!!!!!
I'm going to add an oil pressure gauge to my 05 GTO. Where's the sending unit located on the 6.0 L engine
Remove oil sending unit and replace with a mechanical gauge to check oil pressure
The oil pressure sending unit on the 4.7L engine is right above the oil filter.
In the engine, usually in an oil pressure port
Measures the engine oil pressure and sends this information to the oil pressure gauge.
On the 4.0 L OHV engine, the oil pressure sending unit is on the driver's side of the engine, located below the power steering pump.
The 1986 Chevrolet Cavalier oil pressure sending unit can be found on the left-hand side of the engine. The oil pressure sending unit will be above the oil pan.
They "sense" the oil pressure inside the engine. If you have an instrument panel oil pressure gauge the sending unit sends an analog signal to the gauge. If you have an oil pressure "idiot light", the sending unit turns the light on when the oil pressure is low.
It is on the back of the engine, just to the side of the distributor.
The oil pressure sending unit, on a Chevrolet 4.3 liter V-6 engine, is located on the left side of the engine, just above the oil pan. The sensor is near the front of the engine.

Remove oil sending unit and replace with a mechanical gauge to check actual engine oil pressure
