Iam having problems trouble shooting why my oil pressure gauge is always max. out..

I had that problem, I replaced the sending unit and that solved the problem.[addsig]

Does it go all the way up with turning the key to on but without actually starting the jeep? If so, then it sounds like some kind of electrical or sending unit type of problem.

Here..
Read this, it may help you.

Here's my suspicion...
There is a short somewhere in the wiring for your oil pressure sending unit.
If you say that it shows max EVEN when the sending unit is unplugged, then that would suggest that there is little to no resistance being registered by the gauge.
If you read the article, it indicates that the higher the resistance, the closer to zero, and the lower the resistance, the closer to 80.

Fun, ain't it? :-D[addsig]

Before you go and buy a sending unit check the connection of the wire on top of the sending unit I did and I am working again! Tug :roll: [addsig]

I've had the same problem before too and it is definitely your sending unit,they are relatively inexpensive, so avoid any frustration and buy a new one...
when the sending unit is malfunction it reads the same as a short. If you don't buy a new one right away keep good track of your oil level your jeep will probably be eating it fast.[addsig]
