Well I got the I6 out of the same Cherokee so I would assume that it was the -15. I just asked my dad and he agrees with me. Sorry for the confusion guys. Thanks for putting me back on track. One more question. The EFI I6 from the Cherokee would be a 4.0 instead of the 4.2 correct?

I believe it was out of a 94. I'll double check on that. So that would mean that it was the HO Chrysler Injection

Okay, just got a new lead on the 4.2 engine ghost. It was doing the same thing as before, ran for ten/twenty seconds or so and then crapped out. Didn't really sputter out like a fuel thing but still seemed that way. Been trying to troubleshoot the carb and fuel pump but the other night I reached over and messed with the coil and distributor and the coil was hot as a firecracker. Let it set for a while till the block had cooled off as well and went back to check it. The coil was as hot or hotter than before. Went out and bought a new coil ($16.00 at Advanced why not). Not the way I like to troubleshoot engine trouble or any other problem but I'm scratching my head as are all my other mechanically inclined friends and even my dad. What do you guys think??? As before its a 4.2 with the carter. New fuel pump and it ran perfectly three weeks ago is the part that really throws a wrench in it.

Still nothing. I have been tinkering with it all day. Got it to the point that it idles great for about 15 or twenty seconds and then cuts out. Still can't really decide if it is a fuel thing or not because of the way it cuts out. Also when I open up the choke and look down the throat and open the throttle, it only gives me a good squirt of gas every once in a while. It was only me today so I couldn't get a good read on how the fuel pump was doing. I haven't checked the float bowl either. I'm getting really perplexed here. I could use any help you have.
Also there is a small electrical sounding pop every 8 or 9 seconds which seems to be coming from the passenger side of the block near the cab. I can't get a good fix on it and I remember it happening before the new coil as well. Bad resistor??? Bad ground???
Where would I find the resistor anyway?

Have you Nuttered it yet?
Are you running a regulator? The weber only wants 3.5 psi or your asking for trouble.
On a side note my YJ is running great!

I'm happy for you that yours is running and no I haven't nuttered it yet. I'm assuming you have. That's a weber on yours right? I don't wanna upgrade to a new carb cause I am just waiting on time to swap in the 4.0. But that may take a while. Where did you splice into the wires for they nutter? What else is involved with that? Do I need to do anything special with the vacuum lines? Is it just the wires?

do a search on here for the nutter bypass. i don't have the link right now.
Have you checked your fuel pressure? Are you out of gas?
Do the bypass and let us know if it helps.

I have done a lot of research on the nutter bypass already and just haven't had a good chance to do it. How necessary would it be to reset the timing afterward? I don't have a timing light on me and can't exactly drive down to the parts store to pick one up. I will see what I can do this weekend.
I spent most of today cleaning it up. My friend bought a big tub of these Grime Grabber Wipe things and I just started poking around the engine trying to familiarize myself with it. I just picked a wire or a loom or hose and wiped it down and followed it to the end and checked all the connections and fittings as I went. I covered pretty much the whole thing. I cleaned up a bunch of connections and tightened some clamps. identified the wires i need to splice for the nutter now that i got the oil and crap off everything. and then after i hooked everying back up i got it started. went and drove it around. it died on me and my dad but we got it started agian. we gimped it home. had to keep it kinda wrapped up around 2000 rpm so once it was in the drive way and running i got a screw driver and played with the idle speed and the mixture screws. hopefully that fixed it.
had to take the old man out for his birthday dinner so didn't get to do another test run.

Yes you must reset the timing after doing the Nutter. Go to your local auto parts store and borrow or rent a timing light.
If you were closer i'd give you a hand.

We drilled to holes in the ceiling and looped a big chain around the rafters/floor joists of the attic above and hooked a come along up to it.

sorry I can't post images yet. Still don't have the requisite number of posts.

Your pics need [img] HTML tags, not [url] tags.

The 6 pics in the second quote have incomplete tag info.

At least 1 is clicky-free fer ya!
