A few of the plugs looked wet. Injectors 1-4 all ohm’d ok. Pita to get to 5&6. I cleaned an old set of plugs and tested them, then installed them and it started fairly easily. pic is of plugs removed.

And is there an easy way to check the injectors? Speaking as a novice.......

Update... I tested fuel pressure and it registers 40 psi while cranking. And turning the key to activate pump doesn’t register, and immediately after cranking it drops back to zero.

Here’s another thread on starting issues.... ’92 4.0 4wd last week it ran ok for a short drive. The next day it started and ran for about a minute, then quit. It was very rough, like a misfire or missing a cylinder. now it cranks strongly but doesn’t start, doesn’t even sound like it wants to start. I depleted the battery trying and had to charge it. I confirmed spark on all 6 spark plug cables. I also drained the tank and added 5g fresh gas. I hear the fuel pump activation and fuel drips when I unplug the line at the rail. I plan to test fuel pressure and compression as soon as I get the test equipment. thoughts?

I absolutely love easy fluid fixes! The fluid was low so I filled it and bled the system, and can now shift ok. An earlier major issue with stuck transfer case was also a fluid fix, i.e. the case was empty. I suppose I’ll go now and check the engine oil. thanks all for the assistance.

The only thing I’ve bled on this truck, or any vehicle is myself. But I’ll give it a try. Thanks.

‘92 4.0 manual I depressed the clutch and turned the key, and it lurched forward. I put it in neutral and it started ok. It won’t shift into any gear, and attempting reverse offers lots of grinding. The reservoir showed some fluid so I added to it. I don’t see leaks anywhere. Thoughts appreciated for this Dad who is just trying to run the Manche occasionally for out of state son.

Door hinges welded back on months ago (after door fell off) but door continued to sag like it has for years. So I added a couple of washers to the lower hinge and it appears to shut ok now without having to lift when shutting.

Skanky gas issue again. Sadly this rarely used MJ frequently has stale fuel, it only gets used for a couple of miles a month, at the most. And it needs to have a few gallons in the tank to avoid stalling while on steeply sloped side hill trails. I now only use non ethanol with Stabil, but still have fuel issues. it’s like I need a removable 1 gallon gravity fed tank......

It seems to have disappeared about the time I realized the tcase was dry. That was another issue solved by CC. I can now shift and the annoying squeaking is gone.

skanky!!! I siphoned some gas and added fresh... she’s very happy now. The truck is used infrequently for farm use, so now will have Sta-Bil with all gallons added. Thanks for the great advice.

Update from today. Started and ran for a min but as soon as throttle was released it died. Beginning to think it’s a fuel quality issue. Going to drain as much as I can out and put some fresh gas in and see what happens.

Yes spark is there at ignition and pump stays on. Have not tested timing. Fuel filter is new about the same time pump was replaced in 2015.

I apologize in advance, this may get long. This ole girl started and idled just fine for about 20 min the other day, went to drive off and as soon as I released the clutch it died. That’s where the problems start. The list of things we’ve checked: fuel is present, spark is present, airflow is good, CPS was replaced. It cranks normal but will not turn over. Acts like it is trying to start but something is missing and I cannot figure it out. Then today, after putting in new CPS, took out each spark plug, wiped them off, and she started right up. Idled perfectly (at least for a Jeep) and drove a little even. During the end of the drive, while trying to turn around, it would actually lose power when the gas pedal was hit ultimately shut off and hasn’t come back on today. Acting just like it did the past couple days with not turning over. Please give ideas as to what this could be. Thanks for your time and help. Fuel pump, plugs, wiring harness, distributor replaced 3 years ago with minimal driving since.

A couple of days later........ the owner tells me he never checked the fluid. So I remove the drain plug and nothing comes out. I then filled it, ran it until warm while exercising the gears, then drained and filled again. It definitely is much happier with fluid, still a little stiff to change tcase selection but the manche is again usable. I’ve got cardboard under it now to check for leaks. Thanks yxmj for the fluid suggestion!

Wow, I just checked the fluid level and couldn’t feel any with extended pinkie finger in the hole, and this was with truck on slight incline nose up. I’ll drain and fill in the next few days.

Good idea, though first I need to research the “magnet”. I’m the keeper of the Manche while owner son is out of state. Basically I run it every few weeks to keep it happy, going on 3 years. Skills are slow coming, last year had to replace fuel pump.

I was able to reattach the linkage and shift from 2wd to 4H, and then with great difficulty managed to shift to 4L but it soon popped into neutral. It appears that 4L is not working well, I’ll play some more with it but expect the overhaul will be happening the first week of January.

With a little bit of force I was able to vise grip the tcase into 2wd and then move the manche under its own power. It drove well around the yard in 1st and 2nd. Next I’ll reattach the linkage and see how it works. More than likely when the owner son is home for a week in January we’ll be over hauling it, any suggestions for a good reliable kit?

The linkage was removed a year ago when it wouldn’t leave 4L, a failed attempt to fix it. Now that the tcase appears to be in neutral I’m going to try vice griping again or reinstalling the linkage. Maybe I’ll get lucky.....

I’m fairly certain I need the transfer case over hauled, and I’m positive I don’t have the time nor ability to do it. For the past year the 2wd/4wd linkage wouldn’t budge and has been stuck in 4low. Last week while in reverse there was a clunking sound and now there are no working gears. I can shift through all 6 positions but nothing happens nor sounds when letting out the clutch. Can someone ball park an overhaul? Thanks.

I’m assuming others have listened to the audio, and am quite surprised there are no replies. The recording was made while driving, with no doors, and holding the phone near the driver door sill.

I’ve got a squeaking noise that increases as the speed does. It’s not all the time but fairly consistent. Currently I only have 4x4 low gears available, and typically only ever use 1 and 2. The attached file is from an iPhone, now converted to mp3. Manche Squeak.mp3

I was able to drain the tank and then added 2 gallons fresh gas with Stabil; it started and ran ok. Thanks.

Thanks, I'll give this a try, after I reattach the linkage.
