Oh let me give a little bit more detail, it was the air gap between the end of the crank sensor and the flywheel. The sensor was actually touching the fly wheel. If this air gap is not correct it will throw off the entire car! lesson learn quality over quantity ANY DAY OF THE WEEK!

I had similiar problems with my jeep as far as I can tell it is related to the ignition and alarm, if it happens again and you are stuck somewhere, just remove both cables from the battery for about 20 seconds then put them back on turn the key to the start position and wait for everything on the dash to light up then start the car. since this is the first time this is happening to you, I can tell you it will get progressively worse, the only solution I have found to date is to not use the alarm fob lock the doors manually when you exit the vehical and use the key to open the car, the dealer as always has been useless. good luck

Intermittent Starting Issue by fjnordy

I am having trouble with my 1993 Grand Cherokee Laredo (Automatic 4.0 with 6 plugs). I purchased this vehicle out of a barn where it had been sitting for a couple of years. I was having trouble starting. I.E. would crank for up to three minutes before it would start. I have since replaced the cap and spark plug wires, spark plugs, the crank sensor on the fly wheel. (Boy was that a treat and thank god for having a mechanic for a neighbor and friend helping me!) After not being able to get it to start for a week straight, I was sitting inside the jeep thinking my next steps. I noticed the computer display panel by the Automatic shifter wsn't set. I set the the time and date, then said what the heck "I'll give it a try." The car started after hearing clicking noises from the relays. I have since then noticed that when I turn the key in the ignition, my jeep does its normal bulb checks and starts fine. Yet if the CHECK ENGINE light does not appear when it does the bulb check in the display panel, it will not start. When this light does not turn on, I do not get fuel pressure or spark to the plug.

Random engine shutdowns while driving by veddy

I have been experiencing the dreaded "engine randomly shuts off while driving" problem that seems to plague a lot of Jeep owners with high mileage. However, I'm not getting any codes that would indicate any problems(Just code 12) No check engine light... Nothing.
  
I just took it for another test drive, and it stalled again about 4 miles up the road, however, instead of immediately pulling over, I decided to put my foot in the pedal, and the engine fired right back up and I went on driving.
  
Before when it stalled out, I just pulled right over in fear that if I did anything else I could possibly damage something, but this time I just gave her some gas, and like a light switch it fired right back up.
  
I feel like I'm chasing a gremlin. Replaced fuel filter/Dist cap & rotor/Plugs & wires... etc
  
Throttle position sensor? Crank position sensor? MAP sensor?
  
Any advice would be greatly appreciated.

I had the same problem, after alont of time and money, i figured out what the problem was, the crankshaft postition sensor. Now, this was the very first this I did, and it did not resolve the issue, becuase the crk sensor in on the driverside of the bell housing on top, a few years ago i had a tranny job done, they put in a 1997 tranny in, my car is a 96 so beware what parts your working with.

Just wanted to update my orig. post. So my Jeep finally threw me a bone and the Check Engine light finally came on (prob be the only time I'm happy to see that light...lol) So I checked it and its reading Code 21 (Problem with O2 sensor). I'm going to check the wires and more than likely replace the sensor this weekend. Crossing my fingers and hoping this is the reason for the failed emissions. Keep ya'll up to date after I fix it.

Idle is now bad after installing new CKS by veddy

I installed a new Crank position sensor now my jeep idles like crap. Sounds like it is missing really bad. Like a bad plug or just misfiring. I doubt its a plug or anything else besides the CKS because it idled just fine with the old one but was stalling while driving.

95 Jeep Grand Cherokee Cranks but wont Start by driftnismo240
Sep 26, 2009 (5:53 pm)

Ok I have a 95 jeep cherokee I just put a new motor in. the motor was from a 89 jeep cherokee, the intakes wasn't the same so I change the one of the old motor to the new one. The problem is it will crank but it wont start, but there's a trick it act like it wants to start when you first crank it, but after that it just cranks, but when I pull the fuel pump relay out and try to start it, it cranks a couple of times and then starts up and runs for about 20 to 50sec and runs really really rough, and then dies. Please some one help.
