The oil pump is in the oil pan and needs to be dropped and being a 4WD you also need to drop the front axle pumpkin to remove the oil pan and replace all the gasket needed. Start with the easy and replace the oil pressure sending unit, it's on the back of the engine to the passenger side of the distributor. You can go to Auto Zone and pick up a new Oil sending unit, just make sure your get the right one, "Sending Unit" Looks the same are the oil pressure sensor but the unit reads the pressure, the other just signal a light to go on and off. It's an easy fix like replacing a spark plug.
