Normally if your cat is plugging up you will experience low power with it. If it is gradual you may not notice it though. I think you should change your waterpump. The stock fan, which cools adequately when the rest of the system works correctly, does not make a lot of noise.

Oh jeeze. Just because we're in the stone age doesn't mean you have to come in here and flaunt the magic of your fire.

That P/N is half of the entire vacuum harness setup. The P/N I posted (one digit higher) is the other half. They're about $20 each online. I don't have the P/N for the line from the rear of the valve cover that you broke, but I believe it is available from Dorman also.

Funny thing is I'm having a hard time finding a Renix anything without A/C to steal the delete idler off of for my ugly XJ. Seems like everything that is Renix and base model enough to not have A/C has long been crushed out, save for the MJ in my driveway (and I can't steal that one).

Ehh, sure the perches are centered? That's way out. It's hard for a leaf spring to get out of whack like that. If the shackles are bent it will be very obvious, and even then unless they're folded right over sideways it's not going to do that. Are the center pins of the springs actually in the pin hole on the perch?

And 46004 is the other side of the harness, since it's probably buggered too.

I agree in texas it is a requirement for a/c. So since I bought a mj from canada with no a/c, I have two choices....... move to Canada and leave the truck how it is, or install A/C into it. I'm leaning towards the moving to Canada option. Yeah, it probably is easier to just drive the truck back up here with all your worldly possessions in the back. :rotf:

That's a lot better than it could have been.

Mine doesn't have AC. It is a Canadian truck though. Also came with a block warmer. All the ones I've had 'up here' were without A/C. But I've seen a couple with it. Definitely much rarer in Canada.

You're looking to do a complete HO swap then? Somebody will probably want all the Renix sensors, controls, wiring, and ECM. 88 isn't a desirable year as far as the harness and ECM goes, but it's worth throwing in a box and putting on the shelf.

Or they came loose... Hey, as they say, $#!& happens. Hopefully he's put the new new CPS on and it's running fine. :cheers:

Got any pictures? :waving:

Applies sparingly, yes, should be fine to do that. Make a little round profile paddle (or buy one) to put it on evenly and as minimally as possible.

I could be wrong, but don't these calipers sometimes get a notch worn in them where the tabs from the pads ride, sometimes making them stick? Most often noticed when new parts are installed... Or am I thinking Chevy?

How large is the draw with the key off?

Is there anyone you trust out there, or somebody off here, that could look at it first? The problem with investing that much time/money into a potential purchase is that you will be hard pressed to walk away, even if it isn't the right truck. I don't know what to say about price other than my point on the Peugeot tranny. Beyond that it comes down to "Is it worth it to you?" That I can't answer. It's expensive, but if it's perfect and you want perfect, you may never find another one that's better...

Damn. Did you tell the new owner about this site?

Glancing over it my first question would be is there a bunch of bondo/repaint/collision damage at the back of the cab and front of the bed, just because the rubber trim bumper stuff is missing. Otherwise, looks pretty clean. See if it has a Peugeot tranny or not, price should come down if it's the Peugeot IMHO. And I'm guessing he spent money on replacement stock injectors, too bad. See what type of header he put on it too, some of them are absolute garbage.

No pulse wave modulation jazz, it just has a switched ballast resistor to quiet the pump after start, it's on the fender by the airbox. Personally my gut feeling is the stock pump should be able to produce the amount of fuel you need, but I would recommend checking on Jeepstrokers to see what guys that have comparable power output are running in regards to a pump and fuel system. I think you want a Megasquirt. There is a ton of info on them if you go to their forums. They also make it easy to use on a Jeep 4L as they have pigtails and adapters available for doing so.

What Eagle says regarding the CPS seems to be fairly common. The signal weakens as they heat up, until eventually it's not strong enough to do anything. Check out Cruiser54's tips regarding the CPS and checking the output voltage from it while cranking. Personally I would start with this and I'm fairly confident it will be the issue. If it will start/run at part throttle, the IAC is out. I don't think the EGR is your problem, it normally works as well as it's ever going to on the 4L. But you can disable it by pulling the electrical connector off the solenoid that's on the fender by the airbox; you'll see it fairly obviously as there's two vacuum lines on it and one electrical connector. You could also bypass the fuel pump ballast resistor, it's easy to do, as it's on the fender there also and you can just use some wire or whatever to short across the connector pins on it. Just don't ground it out if you do that. Otherwise it could be a bad coil, or ICM, or an overheating ECM, or many other things. Try the CPS first and we'll go from there.

Yeah, I am concerned that you fried the ECM. If it has a fuel/lift pump, is there any chance you fried it or the fuse for it? That would be not as bad, and it easily would be on a relay that is by the fan one. (No idea what a CRD Libby looks like under the hood, I imagine there's an engine, some wires, and some spinny bits and some stuff.)

Yeah, he figured you were going to be like 90% of CL buyers, ask a bunch of random things and then say "I'll think about it" and never reply again, or "I'll meet you at ...." and not show up and never reply again. Edit, reason I got my XJ for $100 was because I realized the guy was sick of regular CL buyers that don't show up. Let's just say he had a bad attitude about everything to do with trying to sell it. Once I clued into that I just said "I have a car trailer and I will bring it with me when I come to look at it. Does it work if I'm there in an hour?" Suddenly he got real nice. :rotfl2:

Oooo... Any idea what you jumpered to? Were you just trying to bypass a relay? Checked all your fuses yet?

The core is just a simple pass through, it can be plumbed either way once the heater valve is ditched That. ^^^ Hornbrod will probably chime in with which way it's hooked up on the later model versions without the valve. It would be the 'more correct' way to do it, but it won't affect function either way. There is premolded hoses made for later XJs that fit perfectly if you want to spend a few bucks, otherwise bulk heater hose (which I'm guessing you have) works perfectly fine. The premolded hoses do give a very clean look, and I will probably start buying them from now on.

Wow, that's super clean. :thumbsup: Well, other than the missing 'e' - but that's an easy fix.
