1991 Jeep Cherokee Laredo ran smooth until suddenly stalled; would restart for only a few seconds. Visually diagnosed and installed fuel pump; then ran for 2 minutes & rough before stalling. Now we have a new crankshaft sensor; now runs for 5 seconds. We rebuilt one part at a time? Diagnostic equipment not available.
View 10 RepliesGot done driving it one day, parked it, sat approx. 2-3 days, tried to start and it wouldn't start. When the engine was turning sounded like it was getting fire every couple secs but wouldn't fully start. Replaced the fuel filter, tps, distributor cap & rotor, still no luck. Took a look at what color the spark was and it was quite yellow, does it need to be blue?
View 12 RepliesMy jeep wont start if I tighten the distributor bolt, it will start and run fine if i leave the distributor loose. Has been running that way for 2 years and i just was wondering what would cause that kind of problem... 1991 Jeep Cherokee Laredo inline 6 ....

1996 Jeep Grand Cherokee Laredo... A week or so ago we started the Jeep up and let it warm up before leaving for work. When we put it into reverse it promptly stalled. It would then crank but not turn over. After letting it sit for a couple hours it then started fine and has run fine since. Today just a few minutes ago I started the Jeep and drove it to the front of my complex to drop my son off to the bus, after getting back into it I went to put it in reverse and it stalled. Once again it cranks but won't turn over. We initially had thought fuel line freeze the first time, but this time it seems odd having been able to drive it a short distance first..
View 6 RepliesI have a 93 grand cher with 194,000 miles on it. I have never had a problem until now. When driving the jeep sometimes it stalls and then starts back up again and you keep driving. Or othertimes it stalls when you are stopped and you need to start it back up. I had it at 2 dealerships but they can not find anything wrong because it is an intermittent problem and never happens when they have it.
View 14 RepliesMy 1990 Jeep Cherokee (automatic trans) will occasionally stall. The engine stops turning, the tachy goes to 0, no power steering, no power brakes. After I come to a stop I can always start it right back up. The previous owner suspected it was the ignition switch because the vehicle was stolen multiple times, column broken, etc. but I took the switch out and everything seems good and tight there. I tested the switch, not connected to the lock and I couldn't get it to duplicate the problem. It locks cleanly into each position. Start position has strong spring. I tested all the positions with the ohmeter. I drove around with the switch disconnected from the lock and wiggled it as I drove and I couldn't get it to stall. Sometimes I can go days without a problem and other times it will do it three times in a mile long drive.
I've searched the Internet for an answer but all the other posts about stalling the owners have trouble restarting their vehicle. Mine has never failed to restart after stalling. When it stalls it is a sudden loss of engine, no coughing or sputtering. The tachy drops to zero along with oil pressure, etc but the radio, lights, etc stays on. If I wiggle the key in the ignition I can't get it to start back up even if I'm coasting along at 40 mph. I have to turn the key back to the start position.

Problem "Stalls at idle and at hwy speed" sometimes starts right up and sometime will not start. Sometimes it will lose acceleration but engine will still be running and you can punch the gas and it will go again.
It has been in the shop for most of the last 2 months. Driven in 3 times and hauled in twice.
Low mileage 70,000 - has been great until now - serviced regularly.
Did get new fuel pump only about 10,000 miles ago do to starting problem but in that case it just did not start.
Independent shop replaced distributor cap, rotor, coil, fuel filter. No codes and couldn't duplicate problem.
Jeep dealer replaced fuel pump (they said wiring problem), O2 sensor, engine module no help, they asked us to pick up car because it ran fine. It stalled within 2 miles of shop.
We replaced gas cap just in case.
Limped back to shop to replace crank sensor as it was suggested several places. Ran fine for about 45 minutes then back to old tricks. Relays have been checked. Still at shop trying to trace problem. At least nobody is saying they can't duplicate problem as it now stalls all the time.
I have a 2000 Jeep Cherokee Classic with 214,000 miles on it. Ok......this hasn't happen too often, but scares the CRAP outta me when it does.The other day, it happened twice. Traveling on the highway, 65 - 70 MPH, the car suddenly jolts with a loud BANG!I've had the transmission fluid flushed.Each time I go in for service at my local garage, I have them check ALL the fluids. They never find anything. And are at a loss as to what it could be. They've dropped the pan and found nothing wrong with the transmission. No metal in the fluid. They've check the rear diff. Still nothing. I've gone about a year without the issue until this past Monday when it happened twice. I'm a little paranoid to go faster than 60 - 65 right now.
View 15 RepliesI have had no problems out of my jeep except my check engine light came on and it was a bad 02 Sensor and I was told I didn't need to replace it. Well I was driving down the highway and all of a sudden my jeep died. The radio cut off my air and I put it in neutral and I tried to start it and it would not crank. I coasted in a drive way and it cranked and them died. Now it acts like it wants to start but it wont. Replaced the fuel filter. I am getting fuel to the fuel rail. It will not start with starter fluid. I took the crank sensor off and it replaced it and it still wouldn't crank. My fuel pump makes a whinning sound. My lights come on..My windshield wipers won't. My radio doesn't work and the inside lights well I couldn't get them to go off before I before my vehicle died on me, about 3 weeks before I just took the bulbs out. Would the 02 sensor make it not start?
View 14 RepliesI currently have a 1997 jeep grand cherokee that I seems to die on me. I will charge the battery to 100 percent and its actually a good battery. The vehicle will run fine and then out of nowhere it wont start. I throw the battery jump box on it and it starts. I was thinking that something has been obviously drawing power from the battery. What it could be?
View 1 RepliesMy 98 cherokee sport(xj) 190k has always been reliable but now its hard to start. I must press on the gas pedal and rev it up so it doesn't die. Never has done this, after a few revs it seems find. Is my fuel pump bad.?
View 2 RepliesThis past week when I went to leave work my jeep would not start. It would turn over once, and then die....but if I kept my foot on the gas and kept the RPM's up it stayed running. So, I drove it home with one foot on the gas and one on the brake so it wouldn't stall out on the road. The next 2 days the same thing happened when I went to leave work. It starts fine the rest of the time, even first thing in the morning when it's cold..
View 1 RepliesThere was one message that I found like my problem, but a little different. When I turn the key it won't start, just sounds like it is going to start. I turn the key the second time it will usually start. sometimes it takes 3 times.
View 14 RepliesI recently had some wires fixed under the hood of my 1997 Jeep Grand Cherokee, because it wouldn't start. The mechanic told me that it looked like a squirrel had been making a nest under the hood and had chewed on some wires. I suspect that it may have happened over a long period of time, but I'm not positive of that.
Since then, a couple of times it has not started. I get in, turn the key, and all I hear is a click (not a repeated clicking).I've been able to get it to start by putting it in neutral, pushing it forward a foot or two, and then putting it back in park and turning the key again. When I do that, it starts right up. if you happen to know what part of the starter system is most likely at fault.
I have a 1997 jeep gran cherokee 4.0 it takes spells that it will start missing and then quit and will not start but a little later it will start and the code is number 43. Also it will backfire and destroy the muffler. I have replaced the coil and the crank sensor and muffler of course two times. This is not something that happens with heat. It will do it when it is hot or when it is cold also replaced the engine control module or brain. It may do it often and it may run for months before it does it. Again always code 43 when it sets a code what is wrong ?
View 7 RepliesI have a 1996 Jeep Cherokee (sport, six cylinder, 4WD) that won't start occasionally. 98% of the time, it starts up without problem. When it doesn't work the scenario is: put the key in, dash lights up, begin to turn the ignition switch, and suddenly the whole system looses power - no lights on he dash and of course, no cranking of the engine. If I try again immediately, I either get nothing or maybe power until I start to turn the key. If I wait ~5 minutes and try again, it fires right up. This has happened in various weather conditions.
Another problem that might be related is that about 40% of the time, it cranks but won't start in PARK. If I switch to NEUTRAL and try again, it fires right up.
My husbands jeep is driving him crazy. He drove it to work and started fine. Then went to start to come home. Nothing. No crank, no click, nothing. Towed home. Battery OK. Anyway, he put new starter on. Started up. I drove it to station. Got in to come home. Nothing. Same darn thing. We jumped it. Pushed it out of way. Started. It's done this many times. Let me say, though, he went through a huge amount of water before this happened. Gauges went nuts for a while. Don't know if this could've messed up a sensor. He's losing sleep over this.
View 1 RepliesI've got a 1998 Jeep Cherokee Sport 4x4, 4.0 L I6, automatic, 169k miles, that often cranks but doesn't start up. When I cut the power and try again, it starts up right away. I'm concerned this workaround will one day not work and I'll be left stranded, so I'd like to fix this if it's cheap and easy. The symptoms suggest either a lack of fuel or lack of spark due to an electrical problem, so I replaced the ASD (auto shutdown) and Fuel Pump relays, but they made no difference. The other two relays - Starter and Cooling Fan - seemed irrelevant. What this could be? Maybe the crank angle sensor? (I'm not even sure where that's located.)
View 4 RepliesMy Jeep will not start. I can put the keys in the ignition and try to start it and nothing will happen. No sounds, clicking, nothing. The battery is fine, I replaced it with a new one, made sure it was charged and nothing happens when I try to crank it. The interior lights dont come on when I open the door but if i turn them on, they come on but they are very dim. Automatics locks dont work, horn doesnt work. I tried to jump start it with the new battery in with my other car. It tried to turn over but wont come on. It just sounds like the battery is dead when I try to turn it over. The vehicle in question is a 98 Jeep Grand Cherokee Laredo.
View 5 RepliesMy 2000 Jeep Grand Cherokee Laredo won't start...It cranks strong but won't turn over..I can hear my Fuel Pump kick on from the back of the Vehicle but it won't kick on listening from the engine compartment??I checked all fuses.I had a tune up a couple of months ago..My check engine light was on before the tune up and my mechanic said that the tune up corrected the problem the car was coding out... I've been told to check the ALARM by turning the alarm on and off and also unlocking the car Via the driver door.. This didn't work.. I've been told to check the Fuel cut off switch(RESET BUTTON) for my make and year but can't seem to locate it...
