Is this 12k worth of Comanche? Really thinking about buying this week, and obviously ponying up on the cash for this one.

Then the fuel pump hot and/or ground wire has an air gap caused by whatever you removed. Follow the wires from the fuel pump and see where the break is. BTW, what model/engine/etc. is/was the truck? It's an 89 4.0 auto 4x4.

Unscrew and remove the left tail lamp from the fender. The ground connection is a sheet metal screw fastening several wires, including the fuel pump ground wire, to ground behind the lamp. No tail lights or bed sides were on the truck when I got it but it ran fine til I pulled the bed off.

Unscrew and remove the left tail lamp from the fender. The ground connection is a sheet metal screw fastening several wires, including the fuel pump ground wire, to ground behind the lamp. The bed skins were cut off by a PO and they were using it as a flat bed on the farm. So no tails light, all that was there was the bed floor.

I pulled my mj into the garage yesterday to pull the bed off and now the fuel pump won't come on. I read where there's a ground behind the tail light, I don't see any evidence I ever had one of this truck. I read where the relay is located, swapped them out with others from the rack, still nothing. So number one is how to I check my voltage at my relay center? I was getting like 4.2v there yesterday but I'm not sure I was checking it right, however I was getting that same reading at the fuel pump disconnect. I'm trying to find the resistor under the hood by the headlight relay? I read its white, does anyone have a picture of it because I'm just not seeing it. I ran two wire from the batt. Straight to the fuel pump and it fires right up and the truck runs normal. Where does the relay center get its voltage from? Thanks guys!

They should all be the same, I'm pretty sure.... ?

hahaha trust me the light and the front bumper will be the first things to go once its in my hands.

That's correct, it would be basically just swapping sheet metal from one MJ to the other. As far as the 91 frame goes, it should be good (it was when I owned it.)

I would agree and that's def not out of the question. The 86 is an auto, I'm assuming its an AW4 or were they making AW4's that far back?

and here is the 86 I bought to use as the donor truck...

the day I sold the 91 to them 2 years ago...

here's the 91 now...

I am talking about taking all the panels off the 91 except obviously for the cab, and replacing them with everything off the 86. Bed, fenders, doors, etc. I haven't decided if I'm gonna go with a 97-up front clip yet, I kinda dig the old style headlights and grill myself. The 91 is beat all to hell now. Itll take some time but I think its worth saving. One thing I was wondering is do the unibodys on these trucks twist/flex as bad as the XJ's do? That's the only thing that worries me is taking all the old stuff off and none of the 86 stuff lining up due to the 91 being taken offroad so much. Ill upload some pics of both the trucks...

I bought an 86 lwb over the weekend with a solid body, striaght for the most part with a few dings. Two years ago I sold a 91 lwb metric ton package truck and that owner still owns it. It's been beat to gel since then. I would eventually like to have a clean lwb truck. Do you guys thinks it's worth the time of swapping everything off the 86 to the 91? The 91 has 154k on it. I'd post some pics but I'll have to host them and can't do it from my phone...

I would rather use tube but Ive got a harbor freight bender so the dyes are for pipe, plus pipe is easier to come by for me than tube. Ive made several sliders and bumpers out of 1.25 pipe and they held up fine, just never used the 1" stuff before.

What are ur opinions? Too small? Reason I ask is the mj is on 33's and I'm not going anything bigger. I figured the 1" sch 40 pipe would tuck a little closer to the rockers since it's only on 33's. Or would you go ahead and build everything out of 1.25" pipe? If anyone has some 1" sliders or bumpers post some pics!

Nailed it. However lining the power steering pump back up was a pain in the butt. Coulda used another set of hands but I finally got it. Thanks y'all!

Thats what Ill shoot for then! Thanks!

Moving it to the center of the bed but closest to the cab is the idea...

So Ive been considering linking the rear of my MJ. Ive got my own budget way Ive done on a few Cherokees and it works well. With budget in mind, keeping the factory gas tank is something I would want to do. Has anyone moved it into the bed, toward the cab and allowed the tank to sit on the pench seam rim that goes around the tank? Ive done this on several Cherokees but not sure about fitment issues with the MJ's...

might have missed it but what springs did u use on the rear?

My 91 4.0 longbox threw and shredded the belt last night. No diagram under the hood. Any of these look familiar? It is an AC truck... these all look similar. Guessing this is what I need, each one just just a little different from the creators perspective...

Picked this up over the weekend. 1991 long box, 4.0, 5 speed, 163k. Was told by PO it has the metric ton package. Also has a factory front/tcase skid plate. PO installed the 97-up front clip, 3" BDS lift and 33" KM2's. Its been lighly wheeled, should make a great weekend wheeler!

I ran them on my TJ. Just wanted to see a couple different variations on an MJ. Hope to have them on it in a few weeks but with a 3" BDS lift wasn't sure how they would fit.
