    Brake issues on a 89 XJ

    I recently replaced the master cylinder on my XJ due to a complete failure, pedal went to the floor. Jeep had sat for 10 years prior. The brakes were bled and brown brake fluid was forced out, new brake fluid installed. Taking the jeep out for a road test I had a very firm brake pedal with...

    Key Ignition Takes Several Tries To Start

    I have a no crank condition in my 89 XJ. Funny thing is I started it this morning to let it warm up and it started fine. I went out this afternoon to go do some errands and I turn the key and I get nothing. I may shoot some brake cleaner into the ignition cylinder to see if the contacts are the...

    Weird Cooling Issue havent read anyhting like this?

    Here is a great fix to this problem, I myself have a 89 XJ and I could never find a cap that would last holding the pressure in the bottle. Being that the bottle is made in Spain? or some other foreign country the threads are metric. I also owned a Volvo 240 turbo a long time ago. I simply...

    starts, runs for two seconds, dies

    I have found and fixed the problem with mine. Turns out it was a bad fuel pump relay. I swapped the relays without looking at the number of blades on the relay. Three of the relays have a five bladed connector, one of the relays only has four blades. I swapped out, by mistake, a five bladed...

    Motor Swap

    Should be a direct swap, you can use up to 90 for the swap but in 91 Jeep introduced the high output and with that came some changes. Let us know how it goes

    fuel pump woes

    Shorty, thanks for the reply, I swapped out the ballast resistor today and still no start. I actually thought about the switch when I was out for a mtn bike ride tonight. I will shoot some contact cleaner into the switch and maybe that will do the trick. Again, thanks for the reply

    fuel pump woes

    I did a search and couldn't find an answer. I have a 89 XJ 4.0, I have been trying to nail down this intermittent starting problem that I have. It starts, runs until you release the key, then dies. Occasionally it will continue to run. I was doing some trouble shooting today on it. One...

    starts, runs for two seconds, dies

    Hope someone can tell me what this is so I can drive to work tomorrow. I have had a bad startng condition for the last few days. My 89 XJ 4.0 auto starts fine time after time but shuts down within a few seconds. Crank it again, fires right up, shuts down. Occasionally, it will continue...

    did a little swapping!!! a few pics

    Ha, you live in the same complex as me, ever notice the dark blue XJ w/ 3" lift and the roof rack parked up on the next street above you?? I guess I will have to stop by an intro myself. I rode by on my bike and checked out your XJs the other day. You still had the grey one parked behind the...

    Crazy Pressure Bottle

    If you want a guaranteed no leak ever cap for the pressure bottle, go to the local Volvo dealer and buy a cap for a Volvo 240 turbo, 740 turbo or a 940 turbo. Volvo uses a pressurized bottle that is similar to the Jeeps bottle. I have had my cap on there for a few years and it has not leaked...

    Engine Replacement

    First thing that comes to mind is swapping out the flex plate for a fly wheel. There is no hole on the flex plate for an automatic. Other than that I would think that it would be a pretty simple installation. I maybe wrong, if I am I'm sure someone here will give you the correct info.

    Fixing headliner

    do a search for "headliners" on this site, you will find more than enough info on how to redo your headliner. YOu say that it is starting to droop in the corners, this is just a start as to the whole thing coming down. Use a few straight pins to hold up the headliner if it bothers you but be...

    sea foam engine treatment

    Langer, I did force the butterfly open with my finger, didn't use the linkage to do this. Did I throw the IAC out of adjustment with that tactic? Can I re adjust or do I buy a new one??

    sea foam engine treatment

    just purchased a can of SEafoam engine treatment. I poured 1/3 of it in my TB, then I poured some more in my crankcase then I dumped the balance in my fuel tank. I have two questions for the users of Seafoam, first, on the can it says nothing about the duration in which to leave the SEafoam...

    Can a distributor squeak?

    Squeak?? Heck mine howled!! I guess the bearing was going out as every time I started it the distributor would howl. I checked it using a dowel and the bearing was shot. I got a new(not remanufactured) distributor for 52.00, what a deal!! I pulled the old dist. out and you could barely...

    fuel pump replaced

    Hey guys, I'm a newbie here but need to ask a question. I replaced my fuel pump in my 89 XJ 4.0 last night, everything went well and after reading the posts in this forum about fuel pump replacement I may have missed hooking up a hose. The hose in question appears to be a fuel return line...
