My 96 cherokee does that. The doors don't lock with the button, so sometimes I lock and shut the door. Later u return and open the door and it sets the alarm (lights flash) and when you start it it shuts right back off.
Typically I can just put my key in the door, lock it and re unlock it and it resets.

My 1997 Jeep Grand Cherokee 4 liter Ladero is not shifting out of 4x4. If I let it sit til the next morning it will go back to 2 wheel drive. How do I fix this?

This pretty much nails it. The 5.2 and 5.9 engines were originally released by Chrysler back in 1967 as the 318LA and 1972 as the 360. They have been trucking along with minor revisions ever since then. The 4.0 is not as old as the V8s, but is none the less capable. While a revised designed engine over the earlier 258 AMC, there actually are some parts that interchange between then, to include cranks in which an old 258 AMC crank can be used in a Chrysler 4.0 to produce 280 cid, which is a 36 ci gain.

Even the AMC 304, 360, and 390s are not bad mills and are very capable engines. Interesting side note on these engines, when Chrysler bought AMC, the adapted all the AMC head/port configurations into their V8 cylinder heads, added a roller cam, and this is what created the 5.2 and 5.9 Magnum engines.

I'll be using some of the advice in this thread to get my '96 GC fired up. Previous owners were in a wreck with it and I'll be playing with the PCM/ASR relationship to get it fired back up.

I have 256 k on the same engine with revuilds on essentials. My only problem with the engine are leaks and worn parts. Running strong. Maintenance is the issue

One of the main reasons for the longevity of the 4.0 is the fact that it has 7 main bearings as opposed to 4 on most other inline 6 cylinder engines that came before it. That means there is only one crank throw between mains so the crankshaft doesn't flex as much. Add that to the fact that inline design is so dynamically balanced that it doesn't need external balancing like a V engine does. Before 99, these engines produced max torque at 3000 rpm and would "pull stumps" as my dad used to say. In 99, they changed the cam profile to provide max torque at 4000 to help clean up emissions.

The eventual demise of the engine had to do with meeting emission standards more than anything else.

Check the transfer case linkage, especially the pivot bushing on the ends of the torque shaft. These bushing come out of their sockets and cause looseness in the linkage. You can get it to shift sometimes if you shift it "briskly" from 4 full time to 2wd on the roll.

Hi. I'm new here. I have a Grand Cherokee Limited 97. The computer got damaged, and I need to replace it. I've added the stiker of my bad computer.
How I should search the part number? Shoud match the entire number P56041 418AB? Or will be enough just with the first part P56041?
Thanks.

1997 Grand Cherokee ltd 5.2 liter V8 2wd - little hard to start one AM, fine driving home. Next AM engine turns over but no start. LED odometer is on (~118k miles), indicator lights on, but no gauges work. Gas light is on but I know that the tank is full. No fire from coil to distributor when engine turning over. Unable to connect to the pcm using odometer reset button/ key switch method, or OBDI key on-off-on-off-on methods. My OBDII code reader is unable to connect with computer, and cannot read the VIN. The pcm physically looks good, connections clean & intact. No blown fuses. I think the pcm is bad; Cheapest replacement around here is Autozone Cordone for $140 plus $70 core. Cordone reportedly does not require reprogram and is plug & play. Info on here has me questioning myself - I don't want to spend the money if it won't fix the problem. No, I do not have a manual. Sound like the pcm is bad to you?.Your thoughts and advice is appreciated!

Hey guys. new to this forum. I have a 1997 Jeep Cherokee with the 4.0 liter manual transmission. and I bought it not running, the previous owner said the ignition coil went out. I purchased a new one and the plug isn't fitting the new coil. But the 1998 coil looks like the plug matches. Has anyone ran into this ?

I just had the same problem. Replaced the Crank Position Sensor. $52.00 at Orielly's. However now I have misfire and a P0204 code. #4 injector. I need to know if I should replace # 4 and or of them

My 5.9 360 has 260k miles.... Not crap. That crap is most often due to lack of maintenance. User errors.
