Now there's an idea. :brows: and my friendly neighborhood JY has several XJ's but the compressor for the 2.5 they might not have . . . . future dreaming

That sounds JUST like my garage :cheers: which happens to be under and OLD oak tree . . . yup shadetree parts changer here

MAYBE that is a problem on mine as well, runs 90% better now than when I first got it BUT.....

Yea, especially the one not easily seen (under carpet, inside someplace where you can't get to) :headpop:

WE NOW HAVE RUNNING JEEP :jump: Replacement ECM went in and IT had the same whine so I changed the fuse links for good measure, no help, changed the negative battery cable (it needed to be changed), ditto, stood there scratching a hole in me head :hmm: and I glanced at the firewall :eek: .....tell me it ain't THIS simple :dunce: The braided ground strap from the block to the firewall is what burned in two (it was on it's last leg anyway and I had to look closer to see the break). New ground wire put on and fuel pump grunted with the turn of the key :banana: fired right up :clapping: I sure am glad I didn't have to tear anything else down for this. Thanks for everyones input on this _____ thing I did (stupid, dumb, klutzy, butterfingered, :dunno: brain cramp, you fill in the blank ;) ) :D

brigarpeon, knowing that I have the key buzzer, can the relays be swapped for test purposes or are they not the same ? The brain is presently out and my Dad picked up the one I called about earlier today (it was on the west side of Atlanta where he lives, I'm on the east side). And here I thought I was gonna have a hard time finding another one ;) , you guys are great, 2 and possibly 3 additional brains offered in just a few hours :bowdown: Hey Jeff, if the harness isn't butchered (like mine is, somewhat) that would be a nice bonus, we'll talk when you have it out.

Thanks Cole , I've got a line on one maybe but a spare one can't hurt since a 4 seems to be a rare breed.

I was afraid someone would say that, I checked at one salvage yard, no luck (they have mostly 6 cylinder Cherokees) The search continues.......

I had thought of that, using a separate blade type fuse block, but the next question would be what size (amp) fuse to put in the circuit, 18 gauge fuse link X 4 (12 gauge on the alternator). I did find out that the ecm is where the whine was coming from, fried, the mechanic at work said his brother did basically the same thing and the same result (no lights etc) and was the ecm. I got it out and will look for another at the junk yard one day this week. An expensive lesson in being more careful before closing the hood from now on :oops: Just in case, is there more than one number that would work with the 2.5 ? The numbers on mine are "EF 89 53004763" on a paper label and "S100801104A Made in France 8839" on a foil type label

Thanks for all the replies, I've always been better at wrenching :wrench: than electrical, never messed with fusibles cause never had one go bad. Funny thing is that in the Army I worked on commo rigs but knew where everything was from school :nuts: In a learning curve here I suppose Tomorrow after work I'll dig under the dash and find the source of the noise I'm hearing (I don't think it's the blower because it is turned off but it does work) I'll do a search but the ECM is above the gas pedal under the dash? Anyway, thanks again for the pointers and tips yall :bowdown: Once I finger out where everything is............. Oh, and the fusibles here feel kinda rubbery, not like a good wire.

An update on my blunder..... I fixed some wiring issues at the battery, no go, still have starter operation and key buzzer, lost everything else :eek: no lights, 4 ways, anything. That high pitched whine (it's almost like a new type buzzer with extremely low voltage to it) is still there under the dash, barely can hear it but it whines when I turn on the light switch and does it momentarily when I turn the ignition on. I now have a wiring diagram, thanks fiatslug, gonna study on this some more I HOPE it isn't the engine computer). Now for the 64 dollar question, is there a way to tell if the fuse link is bad, there are two of them (green) connected to the battery post on the starter solenoid that go to red wires (just like the diagram shows) that feed everything on the truck except for the starter. Man do I feel stupid with this happening :mad: :rant: :wall:

Thanks hornbrod, I was about to head out and start looking for what damage I did. Yesterday I did notice that instead of the usual pump noise the was a barely audible high pitched "whine" that lasted about the same length of time as the pump noise. Chaulk this up as a learning experience or just a brain cramp :oops:

Are you saying that if you don't have this plastic cover thingy over the battery, the hood will contact the + terminal of the battery?? Good Gawd, I hope you're not saying that....... :huh???: Uh, yup, thats what I'm saying and that is IF the battery is sitting toward the passenger side of the tray, I just wasn't thinking this time :nuts: when I closed the hood, gonna get the right sized battery tomorrow. I'm just hoping that I didn't fry anything major (only down about 15 seconds and ignition, lights, etc was off), I opened the hood right back up and didn't see anything burnt or still smoking except the point where contact was made with the hood.

I was not thinking and closed the hood without putting this plastic cover over the battery :eek: :mad: (battery is a wee bit taller than it should be), after opening the hood back up I tried to start it up, spun over but I don't hear the fuel pump charging the lines. Is there a pump relay I might have burnt up? I don't have a wiring diagram and don't know where to start looking (nothing on the fuse panel says "pump"). Does anyone have a diagram so I can trace this blunder of mine?

I didn't mean to be a bubble buster there Steeler, and I agree that there were many toes over the line with that one. The German line :nuts: had and still has me cracking up every time......almost as much as John Belushi asking "....was it over when the Germans bombed Pearl Harbor...."

Hey boy, I'm lookin' for Sheriff Branford. :rant: I AM Sheriff Branford. :mad: You sounded a little taller on the radio. :teehee: What is the world comin' to ? :hmm:

"Maybe you shouldn't be here." "I don't have anywhere else to go."

"Well, what's she wearin' NOW ? A SMILE" :eek:

As promised, a couple of more pics. Fender, door, and header painted w/ white primer (Cherokee rub strip on the door fell off after rehanging on the truck :oops: ). "Re-repairs" noted in previous posts plus fuel line was riding on the driveshaft, :nuts: fixed, new fuel filter, exhaust pipe at manifold tightened, no more leak there :brows: Tail, park, and brake lights now work. Pay no attention to the flat tires, all four will be replaced on the first trip out of the driveway (the hood is a bit warped on the front driver side, get to that later, it latches though)

Well at least I got part of it right :brows: Another sensor, now why didn't I think of that :nuts: should've figured though :roll: OH, while I have everyones attention ;) does anyone have a wiring diagram for an 89 MJ with the I4/4speed, Haynes book has the basics (point "A" to "B") but not much to go on, I need one with plug pin numbers etc. THANKS

..... I did a short search but..... when changing from manual to power steering I figure the steering box fitting is a given, what about the pump. Will one from an inline 6 fit the 4, same or different bracket ?

Well, the taxpayers and our government spent about 20 grand back in '79-80 to teach me how to fix radio and communication systems, I might be able to handle it but not just this minute. I was thinking about an aftermarket gauge set to replace the idiot lights and perhaps (FX you gave me this idea) moving the fuse panel to the glove box away from the clutch master (but that is way down the road). Gas hand even reads funny, when empty (runs out of gas) it reads about half full, put 2 gallons in and it reads full :nuts: Oh well, so much repaired so far and some still to do 8)
