Have a new to me 1989 Jeep Comanche Pioneer, Automatic, inline 4.0, 4x4. Bought it a month ago, drove it 600 miles home and have started the long restoration process. But now it won't start. Have already found some good post on step by step things to check but have a small twist that may change the order or help diagnose the problem. It has always cranked a few times before turning over. Today I needed to move it out of the garage to get to mower. Started it up, usual couple of cranks and it started. Put it in reverse, got it out of the garage and it died... first time it has ever died while running on me, of course I have only had it a month. Now it cranks but never turns over. Not sure if they fact it died, had a long crank in the first place, and won't start help narrow down what to test first. What have I done to in the past month replaced battery - had the wrong size battery in it from the previous owner - so replaced with new correct size battery replaced the power and ground wires with kit from jeep cables, the power wires and ground wires that were in it junk, bare wire showing and destroyed. replaced 2 weeks ago - has started 20+ times since then. installed new radio fixed rear brakes - they didn't work at all and it failed state inspection, so had to get this done. Now inspection is done. :) changed air filter, old one was way past due.

86 mj My oil pressure guage does not work properly, and I can't diagnose it. It reads high all the time. I got out my troubleshooting manual. First step. Disconnect the sensor, and the meter should read high. Check Seconds step. Ground the wire, and it should read low. Check. If it does, Third step: replace the sensor. Check Result: It still reads high. T o my way of thinking, assuming that the brand new sensor is good, somehow the electrical circuit is open, but I can't see how it could be. The only place I can think of is that the sensor itself is not properly grounded, and that seems, well, impossible. I'm open to suggestions as to what else I can try, or should look at. I mean, there i s really is only the guage (which seems to be working) a wire, and a sensor....

Hey guys. So ive tried to figure out why my back lights on my cluster won't turn on and I'm at a stand still. Ive check continuity between the wires from fuse box to cluster and took a test light to the fuse box, checled bulbs, checked the recepticles and even fuses and I'm at a total stop. Does anyone have any suggestions on how I can drive my MJ at night lol. Btw all gauges, i.e. fuel gauge, speedometer, low fuel light, battery light oil pressure, turn signal lighys and high beam lights work. Its only the connectors for the back lights.

Bunch of transmission questions here. To start with, for anyone that might be able to help me, PLEASE chime in, I desperately need help. I picked up an MJ, an '87 4.0 that has a pugeot BA10/5 in it that was supposedly "seized". This was thought to be the case because the shifter won't move into ANY gear. The only play the stick has is what it gets in neutral. However, by turning the input shaft, I proved that it was indeed NOT seized, because when I turned the shaft, the front axle yoke(?) turned as well. So if anyone has any idea why this transmission isn't seized, but isn't able to shift, I would :bowdown: at your feet and kiss your toeses. Here's the only info I know about the transmission: it was obvious that someone tore into it before, and I'm wondering if there's something that the assembler missed :hmm: . Is there a clip that commonly breaks, a gear that's easy to mix up with another that won't allow it to shift, anything like that that anyone knows about :dunno: Also, other, more general questions: Who is the manufacturer of the AX transmissions? Also, I hear the pugeot tranny is crap, and the AX-15 is the best you can get. But I don't hear anything about the AX5. How does the AX5 measure up to the other two in quality? Oh, and If I were to (theoretically) go from a pugeot to the AX5, what has to be changed, and do I need to shorten/lengthen the rear driveshaft? Thank you very much for reading my post. It is getting very close to too cold outside to :wrench: on things here in Alaska, and I need things running before snow. Any help I can get is most welcome.
