Hello everyone, my 1999 jeep Cherokee sport won't start! All it does when I turn the key all the way is make a "click" and then everything shuts off and won't turn back on unless I disconnect the terminals from the battery then reconnect them. I have already tested the battery and it was fine, I have taken the starter off and tested it. It was also fine. I then also checked all the fuses and relays and they are all good! Someone please help. I dont know want else to check.

Been looking at the AUX fan override methods lately, why couldn't you use a DPDT On-On-On style switch and a dummy load(1kOhm resister) to prevent a CEL in the later year XJs, similar to the AW4 mods? Then you have On, Off and PCM control with one switch and a couple resisters rather than hooking up a relay and associated wiring. What is the PCM checking to determine the CEL?

So last night I installed some LED lights on my trunk hatch. I was trying to tie them in with the cargo dome light. There are 3 wires. Pink, purple, and yellow. From what I read, pink is constant hot, purple is constant ground with hatch, and yellow is constant ground with doors. So I spliced into the pink and purple wires. Now when I open the hatch, the led's come on, which is great. They go off when the hatch closes. Great. But when I try to turn them off by pressing the cargo dome light, they just stay on. I was hoping I could use the dome light to turn them off and on. How would I do this? Should I have tapped into the doors open ground?

Mine started doing what you're describing and it ended up being that the soft lead just literally tore apart.

Hi guys the petrol tank on my 95 4.0 XJ is really badly rusted, as is the lpg tank behind it and the tow bar. So 2 questions really: 1. Do Jeeps tend to rust more underneath at the rear? Bearing in mind I'm in the rainy UK and my jeep was parked up on a rural forecourt for 3 years - might have just been partially under a tree or something ...
And 2: I'm planning on buying a second hand fuel tank, painting it and adding some sort of protective layer. The only ones I see are for 97-01. Is it the same fuel tank? I.e. will a 97-01 fit my 95?
Cheers

It hit me like a tonne of bricks in the shower this morning why the petrol / lpg tanks are so badly rusted along with the rear exhaust section, brakes and rear suspension. The guy I bought this off let it stand for about 4 years after he bought it. However, the guy before him had a small boat he used to trailer around. He must have been backing the trailer in to the water and submerging the rear of the car with it...

Having a little idle issue. When sitting still at temp and idling my RPMs with drop and spike about 250, the jeep will lurch and act like it'll die for a split second when the rpms go down. Cleaned out the throttle body (some carbon build-up), checked the air filter (clean), and sprayed some sensor cleaner into the MAF sensor. Stopped for about a day and had a 30 sec to a minute fit earlier tonight. Could the injectors be causing this? The gas stations just changed out their winter mixture to summer mixture gasoline. I'm not sure what could be causing this.

Edit: new Bosch downstream O2 sensor and cat about 1k miles old.
