i have a 2000 cherokee classic , i changed the oil pressure sensor and it was sending good reading for two weeks then it went down again so i assume its the oil pump that is the problem . Just wandering the easiest way to change it?

Only one way to change the pump... Gotta drop the pan.

You verified oil pressure with a mechanical gauge? Pumps don't die often. They're one of the least likely causes for "low pressure", especially on a 2000.

As part of the user agreement, everyone joining this forum should be required to read a statement that says: "if your oil pressure gauge shows abnormally low or high readings, check it with a mechanical gauge before posting any questions about it". Would cut down on a lot of rehashing the same advice.

Noo! You don't think original content got me past 13,000 posts, do you?

Orlo

Ha ha! Yeah. But ya gotta estimate that answer is at least 10% of those 13000+. That and how do you change your AW4 fluid.

Like said never trust a factory gauge legally they can read 20% off.Always double check stuff before tearing a engine down to make sure it needs it.And if your running a fram brand oil filter that alone will give you low oil pressure.
