    95 cherokee sport 4 door 4wd. I had some issues with this jeep dying on my recently. I just bought it 2000 miles ago. The first time it died I was pulling into my drive way in 1st gear as I have a rough driveway. When i came to a stop to talk to the wife it just shut off like I switched the ignition coil. It started doing it more frequently at random times and conditions. It finally quit for the last time a couple days ago and i realized i wasnt getting spark. I replaced the distributor, spark plugs, ignition coil, crankshaft position sensor and i went ahead and changed the fuel filter and fuel pump relay because I couldnt hear my fuel pump. Ive got fuel pressure but still no spark. I even cleaned up the grounds and put new terminals on the battery. Motor will crank forever but will not run. Check engine light doeant even light up when i switch the key to the on position so im thinking they could be related. Im no mechanic but ive got common sense. Thats gotten me this far but now I NEED help!!!

    Joined the forum after your post and just noticed it. Did you ever find the problem? When you said that you cleaned up the grounds, did that include the ground wire for the PCM? Seems like you've already changed all of the usual causes, but the lack of check engine light could be an issue with the PCM or bad PCM ground. Hope my suggestion is pointless and you already solved problem.
