hi all,

some idiot was fiddling with my fuse box and ignition at a garage when i dropped it off for a neutral safety switch
now my stereo and oil pressure gauge arnt working.
ive seen the radio fuse isnt there so thats that sorted but is there a fuse for the oil pressure gauge? cant work out what the guys done.
cheers

does check gauges light up, bc it might be that the sending unit is broken/torn. Shouldn't have touched that either but you never know, it's above the oil filter about 3 inches long. Just look to see if there are cracks and such. Otherwise I dont know either

shelly24

no it doesnt say check gauges. will check the sender unit. thanks

2x on checking the sending unit.

Alot of times the older plastic on XJ's only need you to look at it "funny" for it to crack.

FYI: There is no check guages lights on Pre-97 models. When Jeep updated the dash, they put that particular light in the cluster.

I just replaced the oil pump on my `97 G Cherokee due to the pressure readings on the dash. I was getting pressure readings & all when I first start her, but after a little while, the indicated pressure would drop to zero. If I cut her off & then back on, the pressure would read normal, then drop again shortly thereafter. After installing the new oil pump, I get no oil pressure readings at all now. Going to check out the sending unit now, but is there anything else it could be??

Also, where on earth is the sending unit?? I looked above the oil filter & didn't see one.

Looks like this....


Screws into the block on one end and has an electrical connection at the other

Cool, do ya know exactly where I can find it? Its not in haynes manual. Already price a new unit, but have no idea where to put it.

Should be right above you're oil filter.. I've broken mine twice changing the oil filter.. It's in a stupid place.

Google is your friend...

I'll check again, but didn't see it there before. Does it matter that I have a V8 engine??

XJeepWerks

Ah, yes it does. Cherokee's only came with a 4cyl or 6cyl. I'm not sure where it's located on the v8 model Zj's.

I have the exact same problem with my newly acquired Cherokee. The 88' jeep Cherokee i drive right now was my dads and i have used it allot over the years. Years ago my dads phone charger was always left in the cigarette lighter outlet, the tip is unscrew-able for an inline fuse. Well one day the charger was removed when the Jeep was running to plug something else in. The tip fell out into the outlet, and when a plastic straw was used to try and push the metal piece out , it caused a spark that could be seen and a pop was heard, The oil pressure gauge went down past zero and the radio no longer receives power as well as the cigarette lighter.
All the fuses are ok , including the oil pressure sending unit. I know the oil pressure unit is OK because a mechanic also said that was the problem and replaced it about 3 years ago. Still no go . last year another repair place agreed to attempt to fix the problem (many don't want to touch electrical issues) and said the stock radio needed to be replaced and did so with one from a salvage yard. Problem still not solved.

Because i am willing to bet that Jeep would not make electrical designs where my radio's power would cut out because the oil pressure sending unit went bad. That would just be really bad designing.

I hope you don't mind me asking about my problem in your thread too, i have tried to ask a couple times in the past and never received any advice

By the way Do you have power in your cigarette lighter outlet?

shelly24

i havnt checked the cigarette lighter actually.
the radio and the oil pressure isnt working and ive just changed the fuse weird.
i hate electrical issues!

I think I'll check mine too. The radio kinda works, but it may have something to do with the factory amp.
