oil pressure

i have a 93 cherokee 4 l ho and the oil pressure guage is pinned on high any suggestions how to fix this issue or some one who can steer me in the right direct

When you see this, either the sending unit is bad, or maybe the guage itself. I'd start by replacing the sending guage and see if that corrects the problem.

i am new to the whole jeep thing so i am very unfamiliar where the things are located on the jeep and all where this is the first one i have owned and all so if u would where would i find the sending unit

Google is your friend.....hope this helps:

The oil sending unit is on the right side of the engine, depending on the year it is either on the oil filter adapter or torward the rear of the engine. Just disconnect it and see if the gauge drops to zero. If so replace it.
