well I have a 92 rad conversion in it so maybe I will look into that?!

if I gotta drop the $$$ on the AC I will just have to make a desert sand rally trip

Alright all the wrong info was givin. Take out your condenser and leave the pump how it is. Your pump won't run with no pressure in the lines and you don't have to worry about anything going wrong. You don't need a bypass pulley. If your that worried about it running unplug the power wire to the compressor.

ok! awesome. so it sounds like this should be not too hard to understand once I'm in there gettin it done! tomorrow I will see! My 88 Cherokee didnt have AC and thats the last rad I replaced. Had a buddy do the 92 conversion rad on the 90 and he is too far away to help!

i own a 99 Cherokee sport and just had the 4.0l rebuilt and did my swap. the new motor spins but will not fire. i am getting fuel to the rail and pulse to the injectors im just wondering if i have everything plugged back in right since i was stupid and didn't label anything. if anyone might happen to have a diagram of what goes where it might be super helpful.

thanks to all who can help,

So my belt on my 88Mj popped off the PS pump again.....I've noticed that my Mjs power steering isn't quite as good a the Xj of almost the same year. Could a bad pump cause the belt to pop off? Would running up to 4500rpm 1st thru 3rd do it?

ok 93 xj has a problem (big suprise) it will run fine for ever then get a wild hair up its hatchback and deiced to shut down when it does i have no spark and the wait time is never the same sometimes it is 10 mins sometimes it is hours just depends i dont know what else to do besides the crank position sensor any ideas

long shot, but my '94 used to do this randomly. finally i found out what was causing it: the ground strap that runs from the center of the firewall to the cylinder head was rubbing on the nearby wiring harness and eventually exposed the wire, and would randomly touch the ground strap and short out the circuit. with the engine running i took a jumper wire from ground and touched it the bare wire and sure enough the engine cut right out and wouldnt restart for a little while just like it had been doing.

sh** like that can be hard to find, my suggestion is to start the engine and shake the wiring harness real hard, this will check for loose/damaged wires as well.
also, when it wont start, check it for fault codes.

i have tried that already i will look at that more closely i do not have a check engine light on but when it dose do it and it comes on it only says o2 sensor but it will go off if i turn off and restart the engine.. got me stumped

rompnXJ

you do have a check engine light but its an OBD1 CEL.
turn the key from OFF to ON 3 times and then leave the key ON, the red check engine light will start flashing, and you count the flashes, theres a chart around here somewhere that shows how many flashes mean what.

4.0L ?

daddiesjeep

yes it is a 4.0 i know it has a check engine light it just dosent come on when it shuts down and when it dose come on the ony code i can pull is o2 bank1

daddiesjeep

ok well since it keeps shutting down on me i havent drove it so after charging the battery and letting it run for a bit i shut it down since i had a engine light on yhat wasnt on the last time it blinked 25 time

I need to buy new positive battery cables for my 96 xj sport. I'm having a tough time finding the cable I need on the internet. Probably because I don't even know what it is called. But it is the cable that runs from the battery to the starter. I don't know what to search for.

The only thing that I have found so far is this. http://custombatterycables.com/appli...kee_cables.htm

And it seems kinda shady though. There is a lot of "maybes" in the descriptions.

I believe there is a little green wire that runs along this cable? I'm not to sure about this though. I have never dealt with this before.

And I know I need a new wire because I have traced my starting issue to this. I sometimes go to turn it on and only get a click. I have power and everything. I wiggle the battery cable and it fires right up.
