SOURCE: 2001 jeep grand cherokee 4.0 engine shuts off

it is possable/likely a bad ECTS (engine coolant tep. sensor), this can cause the injectors to allow to much fuel into cylinders and cause a low compression and or flooding situation, good luck, marty

SOURCE: 1996 Jeep Grand Cherokee No Start

I would be thinking that there is a good chance that you need to be checking out replacing the computer, if you aren't getting any communication with the proper scan tool then the computer isn't communicating with anything in the vehicle...... I would have guessed first off that the ignition control module might be bad but that is obviously part of the computer also, I would be looking in that direction.

Jeep cranks but does not start


Hi, First replace your plugs. Second check ignition coil(s) one maybe bad. replace with new. If all else is good, have your mechanic check the computer codes. (code scanner) Many of todays cars and trucks have computers to run and control the engine. (management system). Good luck

I have a 1996 Jeep Grand cherokee with the 5.2l v-8 engine. Last week I started it, and it ran for about 1 minute before shutting off. The engine cranks, but no ignition. I replaced the Crankshaft position...


Time to meter voltage. Start with the 12V circuit. Are you getting voltage at the coil. Does the voltage fluctuate when the engine cranks? If yes to both check the high voltage circuit. Start with the coil then the distributor then each plug. You should be able to find where the spark is failing.

1996 jeep grand Cherokee will turn over but not start. weak spark. fuel at fuel rail. replaced PCM 1 month ago. replaced crank shaft sensor 3 months ago....


See if your getting spark at the ign. coil first (passengers side on that year) if you are change the crank shaft sensor making sure you mount it as close to the engine as possible so it never gives you trouble again.

1999 Jeep Wrangler 4.0L cranks but will not start. No spark from coil. Replaced coil and crank sensor.


Check all your fuses, check power to your coil, I doubt the crank sensor was bad unless it threw an engine light at you. Ohm out your plug cables.

My jeep has issues with shutting off at random times. It can happen when I am driving or idling. If I am going fast, I will lose my acceleration and I will have to pull over. The engine will either pick up...


The issue lies with any of the following three things 1) can sensor 2) crank sensor and 3) ignition coil. Check the quality of the spark at the plugs as a way to check on the coil output. Next some Jeeps have one coil per two plugs and some have coil on plug. If you have one coil per two plugs disconnect the two plug leads to one of the coils (on four cylinder engine they are arranged plugs 1 + 4 on one coil and plugs 2 + 3 on the other coil). Turn the engine over and sparks should jump between the terminals on the coil. If this happens the crank sensor continuity is OK and that it is detecting crank position, if not then this a strong indication that something is wrong with it. Check it for cracks and check the wiring all the way back to the ECU and check the connection is clean. Replace it if suspect. Now physically check the cam sensor. Any cracks or distortion in the body of the device replace it. Check connections and wiring back to the ECU. Generally the cam sensor goes wrong when the engine is hot. If you get random shut down even when starting up this indicates that it is more likely to be the crank sensor or coil.

Won't start no spark, crank sensor checks ok


Hi, if you have checked the crank sensor and you say you have no spark, I would go right to the coil on this jeep and check to see if this may be you're problem. Check each plug wire for spark using a screw driver inserted into each wire while someone cranks the engine and you hold the metal portion about an 1/8" away from something metal. You should have a good spark if the coil and other componants in the distributor are working. Its just a process of elimination. Is you're check engine light on? If so, were you able to have an OBD-2 meter connected to it to read any codes? That's only if it is on. If you have no spark at any of the cylinders, I would be looking at the coil and other related componants in the distributor. Please feel free to keep me posted on this.

1991 jeep wont start


Did you replace the coil because it wouldn't start before? If it ran before, there must be a mis-connection somewhere. I assume by your stating that 'it turns but will not crank', to mean that the engine will crank over with the starter but won't start and run. True?
