Re: Help with oil pressure please.
More than likely is is the sender, they are notorious for failure. But you
should double check using a mechanical gauge you can borrow from your local
Auto-Zone.
When you get a replacement make sure it is a sender, not a switch for an
idiot light.

It could be, but first just change the sender. I think Jeep got the
original units from Lucas or similar. If your sender filter layout is
the same as a 4.0 ZJ, the hardest part is simply turning the thing--you
only get a very very short stroke with a wrench on each attempt. The
change itself other than that is trivially simple. [Thanks DougW]

Re: Help with oil pressure please.
Jeep Talk is what I need. I just found this string and joined. I've got
a 99 4.0 with bouncing oil pressure gauge and "check gauges" light
popping on & off. I think it's sending unit as engine runs fine with no
noises. Just where is the thing located? And can I replace it just by
crawling under it?
Thx
