Oil pressure guage pegged

Hey there all, my oil pressure guage has been pegged past the 80 psi (like it isnt even connected) and before it worked fluctuating from 40-80 so it was still messed up. Well I replaced the sending unit, still no dice its pegged at max. The needle doesnt move in the on position at all. I grounded the wire for the sending unit and the guage will go to 0 right when grounded so I know the guage works. I highly doubt I have 2 completely shot sending units, I plugged the sending unit into my friends cherokee and it works fine.

Any ideas?

did you get the correct sending unit? there is one for the light on the dash for about $5 and one for the gauge for about $15. its just a thought as the previous owner had put the wrong one in on mine and thats what i had.

If you have the correct one and dont have a connection (wire) problem then as stated it likley to be the gauge in the dash i would think.

did you accidentally disconnect it near the oil filter last time you changed the oil?
