if the gauge starts a 0 - goes to 1/2 , than full - sounds like gauge is OK - seems to me like the sending unit is bad - you could try removing the sender and trying to clean out the port with "brake clean", letting it dry than re-installing it. the pressure switch is still the least expensive place to start

if you have the 5.2 V8 its located in the rear of the engine near the dist cap area you can see it if you look in that area , if 4.0 6 cyl its located on the side of the engine block near the oil filter area. It has two wires going to it and screws into the block. It's made mainly of plastic and if broken can allow oil under pressure to spew out and give you thoughts of a blown rear main seal due to the amount of oil all over the underside.

First things first do you have a repair manual? If you don't have one get one, Changing the unit is realitively simple, you just disconnect the battery, disconnect the oil pressure sending unit's electrical connector, remove the sending unit, now most sending units are small and look like a short chubby spark plug with an electrical blade connector on the end of it. simply use a wrench to loosin and remove and install by screwing in and tightening and reconnecting the electrical connecter then the battery and your as good as new!
