Thanks for the info. My 95 XJ has the HO engine so there is only 15 HP difference between it and my 89? What about the 4 port injectors? Got a part number for them? Is there a thread for the Chevrolet engine conversion you mentioned? My 89 from Tennessee has 100 k on it so it will be awhile before that engine will need anything but I do have 2 or 3 more projects in mind.

I have a 1989 MJ long bed 4.0 2wd with a 5 speed soon to be 4wd. I was at the junk yard checking out 2 MJ trucks for parts (tail lights where gone of course) and one of them is a 91 or 92 because it has the injection module by the air cleaner and has the open cooling radiator system. It looks just like my 1995 XJ under the hood. I'm thinking of doing a fuel injection swap with wiring harness and all sensors throttle body etc. Couple of questions. Will I get more HP out of my 89 4.0? Are the injectors in the junk yard truck the 4 port ones that are talked about running smooth and get better mileage? Do I need to get the entire wiring harness out of the truck or just from the firewall block forward? I didn't see a fuel pump resistor in the junk yard truck does that mean I need to switch fuel pumps also? I seem to remember there might not be a return line from the fuel rail. I forgot to look at the junk yard truck. If there is only one line going to the fuel rail then I assume it means that I need the fuel pump for sure. And if that's the case should I just go ahead and get the tank. Seems like I read that the fuel pump mounts might be different. The junk yard truck is 4.0 2wd 4 speed manual. Comments?

Hi Snakedoc67 I sent a PM to you. Waiting to here from you. Are those electric windows original? Or are those Cherokee doors?

Two are short bed but do not have boxes. What you need?

Looking for a complete tan interior for a MJ . Dash, seats,head liner, all trim panels and seat belts. Gabe 517 896 0020

I am looking for a 3 in lift kit for my 1989 long bed soon to be 4 wheel drive. I'm sure somebody has one left over when they went higher. Also if you have the kit would you have a good set of 31 in tires and wheels. People usually go bigger tires and wheels when they go higher on the lift. Gabe 517 896 0020. I'm in Michigan.

Thanks again! I can tell that your list is going to be a good thing to go thru. I noticed a big difference in engine performance by just redoing the grounds by the dip stick. I have a leaking exhaust manifold between the manifold and the head on the front cylinder to fix which will eliminate loose manifold bolts and I need to make sure that the CAT is not blocked. I have a rough idle with a hesitation just off idle and a back fire when I let off the gas. Also engine does not warm up very fast so I probably need a thermostat also. Need to get all of that fixed and then hone in on your list. Got rid of the death wobble this weekend. The cross bar going from frame to front suspension was loose at the frame connection mount. Had a elongated tapper hole in the bracket. Grabbed a used one from my donner truck. Got it out on the Freeway and found out my rear end is going out. Front bearing on carrier is getting hot. I was hopping to use the truck in 2 wheel drive mode for awhile before I converted it. Guess I need to upgrade sooner. I want to put disk brakes on the Dana 44. Will the jeep liberty brakes fit the 44? Do you just get the mounting brackets and buy new disks and calipers? I've seen the bigger power assist for the master cylinder which I intend to do also.

Roger that. So to restate it a Renix system will have a Bendix control module except for the 1986 which has a Renix control module. Did I get it right? Appreciate the education.

List of what I got. Will have to check tonight on two of them 1986 - Renix 1988- ? 1989 -Bendix 1989 - ? 1990- Bendix My 1989 does not agree with Your 86-90 list of Renix. The 1989 is my donor which is completely stripped and I'm 100% sure I pulled a Bendix Main Module out of it. I have to crawl under the dash's tonight to check the other two.

I have seen this page and read it a few times including all of the points. Questions is it is my understanding that the Renix trucks are 1986 1987. I'm sure some to most of these tips apply to the Bendix injection trucks. Am I right that the Bendix injection trucks started in 1988? Is there any thing that I need to NOT do on the Renix list if I have a Bendix system?? MJholic

Typo on my Tennessee truck its a 1989 of course.

Put new cable and a used starter on last night. It cranks much better than before. Got a steering box leak to fix and a rough running engine to take care of and I will have my first functional MJ. It's a 2 wheel drive 1999 long box from Tennessee that is unbelievably clean underneath. I'm picking up my AX-15 ,231 this weekend. Got the rest of parts needed for the 4x4 conversion from my completely rusted in half donor 4x4 that is getting split up between at least 3 trucks. My first truck was a lifted 1986 from Florida. Real clean except for the wire harness fire that took the 2.5 out. Converting it to a 4.0 from the donor. I have figured out on my own and with reading on this site the things that will have to happen to it to get it switched. There does not seem to be a definitive list for this undertaking which I think needs to be available to other 1986 owners. Also a few bits of the threads I saw about the differences are wrong. So If some one could help me figure out how to put pictures up I intend to show and list my conversion process that I'm mid stream into. I got side tracked getting a tow vehicle going because of my kid losing my keys to the Cherokee. I have searched the help section and there is nothing there about picture posting. Need help please. Also is there a place where all of the short hand parts conversion descriptions are defined. I'm a fast learner but what would be helpful is a definition of the part and from which year model jeep the part can be found. Also the vin number decoders are mostly wrong. The one from Jeep all most worked for all 5 of my trucks. I have two 1989 trucks. One worked with the 1989 listing in the decoder. The other one worked when I used the 1990 listing. I saw another post talking about this. So they shifted the codes somewhere in the 1989 production year to the 1990 standard. MJholic

Thanks. I did check the cable just now with an ohm meter and amazingly it has 0.1 ohm resistance from the crappy old battery clamp thru the exposed section of cable to the round lug that goes on the engine block. I was maybe thinking it could be the crimp on the ring lug but that just got ruled out. So that leaves the ring lug connection to the engine block which I can't check now that it's apart. I was going to attach a picture of it but not figuring out how I do that just yet.

Have recently become a Comanche owner. Started two months ago. I'm up to 5 trucks with one more on the way as soon as I get one road worthy enough to go get it. My kid lost the keys to my Cherokee which has been my primary road tow vehicle with a tow dolly. Any way I have two trucks that have about one foot of insulation melted off of the ground cable back from the engine attach point. I'm puzzled by this because of the main ground cable from the battery going to the engine puts the biggest load from the starter directly in the proper current path. The insulation meting is coming from heat. It is either internal in the cable due to current load or it is external from the engine. Because I have 2 trucks with the exactly the same conditions I would expect that somebody else has seen this. The starter on one of the trucks that I can start does sound really loud when compared with my 1995 Cherokee. Is it just a bad starter overloading the cable? MJ Holic
