--Visit profile for picture-- 1992 Jeep Comanche Pioneer 1J7FJ26S0NL163889 Purchase: 3 NOV 2015 I6/ 4WD/ 5 speed 225,560 miles

I recently started working on my 1987 Jeep Comanche 4.0L again and so far I have replaced the crankshaft position sensor, transmission shift cable, spark plugs, plug wires, cap and rotor, fuel tank, fuel pump, fuel filter, and fuel pump relay. Now that I have all these things replaced I was getting ready to get it running and after multiple attempts it would fire sometimes, other times not when we would spray engine starter into the carburetor. We then took one of the spark plugs out to see if we were getting spark and turns out we weren't!!! Before this we checked the fuel injectors and they were all working perfectly, the pressure was amazing on the fuel rail as well, so we knew it wasn't a fuel issue like other people have said it could be. Next we checked the ECM to see if it was messed up internally at all and it was perfect as well. So I am at a stopping point right now until I can figure out what is causing NO SPARK! I heard that it could possibly be the ICM, but I wanted to hear from fellow Comanche owners before I move forward. Please Help!

Hey guys! its been a while since I've been active on here and I wanted to give you guys an update on how mt build was going. So I've finally dropped the engine into the Comanche as of TODAY i have a few pics so ill start with that. ENGINE INSTALL: So I had decided to put the 4.0L I6 back into the car since the previous owner failed at doing a 4.3L v6 swap from a Chevy s10 (failed because he didn't put enough effort into the wiring and thus had several problems such as the entire gauge cluster not working, no high beams, and oh yeah, the thermostat was effed up and the heads blew) so once i finished absolutely gutting it, Ive been cleaning, painting, and buying parts for the new engine ever since. PLANS: I am going to finish up either this weekend or next by putting in the Aisin-Warner AW-4 four-speed automatic. I just need a transmission jack I need to swap the axles and do a whole suspension upgrade starting small with things like bushings and hardware. I plan on working my way up to stuff like shocks, coils, and eventually finding out how to get rid of leaf springs for something better. PROBLEMS: The. Seats. I have been looking up the bench seat to bucket conversion and taking the bench seat brackets seems not safe to me (probably because I'm an idiot lol). If anyone has any suggestions on that plz lmk. I've been looking at the threads as much as i can. The roof has been nothing but stress. I removed a god awful sunroof someone had put in even before the previous owner. I'm at the point now where if I see a Comanche at the junkyard i may just have to bring a generator and an angle grinder and take it.(also open to suggestions on this one please please) the heater core. on the donor xj i bought there was a really nice heater core and I messed it up trying to get it out. The bolts that hold it to the firewall were on too tight and when i began to pull it destroyed the plastic. For this I'm planning on trying out plastic welding it since the actual heater core is in excellent condition. just the plastic is messed up. The list goes on and on (as always). I appreciate all the elp you guys have been so far and I can't wait to keep adding stuff to my portfolio. I will try to post once a week but work and manche time take up most of my days.

Good morning to all! I was curious as to which transmissions will bolt up to the Jeep 4.0. Right now I believe there is a Chevy trans connected to the vortex swap the previous owner did (haven’t ripped into my MJ for a swap yet). Appreciate the help this far guys! Love the website also quick side note I was told I need to do 10 replies or posts and I was just curious if someone who is a long time user of this forum could clarify that for me

I'm looking to purchase a 1988(birth year) or whatever year. Preferably with no rust & no major work to be done.
