I just read an article on MADXJ but they were using a 89 XJ. My 90 looked different than the 89 pics they were showing... I hate that pump over on the passenger-side fenderwell.And an ABS box under the rear seat. So if I can swap out the brake system from a 96 XJ, can I get rid of all that...

If I were to swap out the rear from a CUCV (D60?), what would a equivalent front axle? I see the CUCV has the diff on the wrong side?

The rule at most auto stores is "No return on electrical parts" so I was stuck with everything I purchased prior to the CPS... But at least I can safely (?) assume those new parts should last another 15 years and I've got some spares now! If you drop one or both of those CPS bolts during the...

No kidding... You would think somone at Jeep would:gag: Wait a minute, what was I thinking? Of course they would NEVER fix all these problems at the factory! $$ I have a 90 XJ and it seems like everyday I'm on here searching for the latest issue. First the "No Spark" thing (Replaced the...

Has anyone swapped out a 90 XJ brake system to something more modern? My brake system is going to shit & the pump is running all the time now. Yes, the fluid is full... One of those "I woke up this morning" things. I'd like to rip out the entire POS system and go with something else. I...

I have access to a CUCV and a F-350 4x4. Which of these rear axles would be better if I chose to go that route? What about the front axle if I decide to use one of these full width rear axles? The CUCV front axle has the diff on the wrong side so that's out... The F-350 axles look kinda weird...

Welcome to "The Club"! LOL I have threatened my 90 XJ with the junk yard almost on a daily basis... And I only drive it about 2-3 times a month! (H-D is my DD) But I am determined to not let it kick my ass, much to my wife's confusion. She keeps begging me to junk it and pay $50k for a new...

I was wondering something along the same lines for my 90 XJ. I have access to a CUCV & a Ford F350 4x4. Ford axles look kinda weird, especially the front linkage. CUCV front axle has the differential on the wrong side though... I need a rear axle at a minimum...

Has anyone replaced the RENIX ignition system with a better one? I hate getting in my 90 XJ and cranking away... There has to be a better solution. RDX4ME:hang:

Wish I could help you... I USED to think I new something about automobiles but since I bought my 90 XJ I'm as lost as you.

Just replaced the CPS on my 90 XJ. Sort of a last ditch effort to get this thing going before I come home one day and they wife has sold it! I've replaced everything the manual and NAXJA Forums has discussed concerning "No spark from coil" threads... Replaced the CPS and it did look a bit...

OK.... I've been searching for most of the day (Yes, I did use the "Search" bar) trying to find out which lifr kit is regarded as one of the best for the XJ? I plan on running 33-35 tires. Not alot of rock climbing in NW Florida but there is plenty of sand and red mud towards Alabama... 1990 XJ...

How about Massengils then? LOL!!! Sorry, couldn't help it... :)

Not...

Just bought a CPS for my 90 XJ 4.0 because I too stopped getting spark off the coil. Cost me $34 from Advance Auto. Will be putting it in tomorrow & will let you know if that was the problem. I have already replaced the coil, ICM, plug wires, dist & rotor.

I know how you feel... I have a 90 XJ 4.0 and I might as well be driving around in 4WD all the time. Mileage is around 10-12mpg regardless of tune-up's or anything.

I picked up a CPS at Advance Auto and will try and swap it out this weekend. I'm getting no spark out of the coil... Thanks for the info!

But what would prevent spark coming off the coil after replacing the coil, ICM, CPS, etc, etc...?

Is there a FSM download on this site? My Haynes manual didn't even show a CPS for a 1990 XJ 4.0

This afternoon I stopped by the local O'Reilly's autostore to pick up a CPS since I've also been having spontaneous spark / no-spark coming out of my brand new coil / ICM /wires /dist & rotor /etc... I figured better safe than sorry (stranded). The parts guy could not find a Crankshaft...
