#203 of 275 1996 Jeep Cherokee turns over but won't start- no spark by joes96jeep

I have a 1996 Cherokee Sport with a 4.0 L engine. Car was running fine one moment then when I went to start it 20 minutes later it just turned over but wouldn’t kick in. No spark. So far I’ve change the crankshaft position sensor, the Powertrain control module (or ECM) with one from a reputable junk yard, the coil checked o.k. after I took it out and had it checked; the rotor cap appears fine. I don’t hear the fuel pump kick in like I believe I should when I turn the key on. Another thing I noticed that I don’t recall hearing before is the electric cooling fan runs when I turn the key on, which I thought is odd, since the engine’s cold. I checked the relays in the engine compartment and they all seem to be fine? Any thoughts? I think the only way I can check the PCM is to find someone with the same vehicle and swap out and see if their car runs, unless some has another idea.

I've got a 1996 Jeep Cherokee, runs alright but here lately mainly going up mountains it will just quit, had it out yesterday and it quit twice. Went out this morning to take a look at it to see if I could see anything wrong with it and now it wont start. Tried a new starter and still nothing! What should I look for?

My son has a 93 ZJ and it too would just die for no reason. After some time we found out that the coil MUST have 300+ ohms or the computer shuts it down. After changing out the coil the rig has never died again. Hope this helps.

#207 of 275 01 Cherokee baffles mechanics stalls when stopped by hall4sc

Aug 24, 2010 (11:53 am)

Hi I have an 01 Cherokee that is baffling my town mechanics. It stalls out when the idle is at 1,000 rpms. The oil gage has also started shooting up to 80 for no reason. The computer doesnt have any memory and sends the mechanics comp crazy. I have recently put a new battery in as well as a full tune up. The car had been sitting for a few months not driven in the desert. Drove great for a few weeks and then this. I dont want to spend a ton of money on a new computer when no one really knows WTH the problem is. Anybody had this happen. And what does a computer cost anyways. Thanks

#208 of 275 PLEASE HELP: 96 Jeep Grand Cherokee Limited by niesah

The past few weeks, my Jeep will sputter when I first start it in the morning, then after 30-45 seconds, it will straighten up and be fine. It's also done it when I've started it when I leave work, or if I have to leave at night, pretty much anytime it sits for a couple hours. Also, when I roll forward (like waiting for someone to pass so I can turn left at a stoplight), it will sputter like it wants to die, and I have to give it gas. We changed my spark plugs, my distributor cap, cleaned the MAF sensor, and nothing has helped. I thought it could be bad gas, but I have a new tank of gas from a different gas station, and I put a can of Sea Foam in it. We really don't know where to go from here, so if anyone has ANY suggestions, PLEASE let me know!! Also on a different subject, my jeep will hang back sometimes when it shifts into the next gear. I'll have my foot on the gas when I'm pulling out of a parking lot (for instance), and it'll hang back, and then all of a sudden it will kick in. It also feels like it's shifting kind of hard...I'm really hoping that my transmission isn't going out on me. I just rolled over 160,000 miles on it. I don't really know what the upper limit is on jeep mileage, but I'm afraid I'm getting to that point. If anyone has any ideas about any of the above issues, I'd really appreciate it. Thank you!!

#209 of 275 1990 Jeep XJ stalling with slight acceleration fwd and rev by chadhlms25

Oct 17, 2010 (12:25 pm)

I have a 1990 Jeep XJ, when I slightly press the accelerator the engine sputters and stalls on me. For instance, when im in a traffic jam and I creep forward, it often stalls. It also does it in reverse. The only way to avoid it is by accelerating quickly; I can manage doing this if im moving forward but it doesn't seem like a great idea to floor it while backing out of a parking space (if you could imagine). I was thinking it could be the fuel pressure regulator or the fuel pump sock is full of crud. I recently had the fuel system cleaned (including injectors) and replaced the fuel filter. Has anyone else had the same issue corrected, and knows the culprit?

It is possible that the connections on the computer have gotten dirty,take battery cable off then remove plug to computer check and spray with contact cleaner.Replace plug and put battery cable back on. Hopefully this will fix your problem.I had similar problem on a cherokee.

#211 of 275 Jeep Cherokee Problem by casteel11

Oct 25, 2010 (12:41 pm)

When I start up my jeep and put it in drive and start going the engine seems sluggish and i can press the peddle down as hard as possible but it doesn't want to accelerate until a few seconds later. After it gets going it doesnt do that anymore its only on start up. I dont know if it would be my plugs or not. Any help would be nice so I can get this problem marked off the list. thank you

Your diff's should be a 30 front and 44 rear, pretty standard on grand cherokees however they sometimes changed those, look on the pumpkin of the diff's for a tag. it should be stamped with the modle of the diff and the ratio. the ratio's will be identical on both axles.
