moved you to JEEPS, from computers
just sold mine, 2002, (sad I did 2008 stinks)
first of all, in English,
no engine size told,
nor what country sold new, Jeeps are made all over the world now and for sure no the same (not engines or electrics, nor EFI)
petrol or gasoline ?? later is USA name, but translaters lose that fact.
pu j'ai de l'essence qui == gasoline or French Petrol>?>>>>>???
are you in Europe or france or in USA or canada speaking French.
all that is good and fun sure.
but cars are not the same on earth, for a fact.
I can not look under your cars hood nor read your VIN.
English answer + translated.
Generic 100%
On all our cars USA ,I spark dies , the PCM cuts fuel.
yours did not so may be just flooding fuel engine.
are all 4 spark plugs dripping raw fueL?
ever replace the spark plug or are the 20 years old?
50k miles max is the rule , 2002 engines smoke so is less.
on spark plugs life. and gapped correctly
the owners manual on the car tells now to clear flooding
(spark good)
put throttle foot to the floor, WOT.
turn key and crank and fall fuel injections are cut, and now tries to start. (5 seconds max) on starter spins.
but fails, now repeat with no foot actions.
see it start and run. now
if not engine needs service.
way 2 , new spark plugs and all 4 tested for live spark first.
we then remove the fuel pump relay or fuse
and crank engine over using test fuel in hand
see scotty do that we love him here.

I got a 2007 jeep grand cherokee diesel and at times the service park assist will flash and the engine light will come on. a box forms around the gears on the display and it feels like it trannys slipping and its rough out of 1st gear. if you throw it in neutral then back to drive everything is fine again. After hours of research i found that you have to get your computer flashed. It if commom for many people and the dealership wont know what your talking about. so you have to lets them know!!!! else they have no clue
It would be more cheaper to buy a new car than to try and fix the car that is broken. Both the alternator and the voltage regulator need to be replaced for your car.

Also I
have a GC, 1993, and I noted that besides maintaining a vent hose that
is not going anywhere, just this subject with a ribbon next to the front
suspension. Hope helps (remember rated this).
Likely a ground has corroded and failed. A simple test is to take a set of jumper cables and create a temporary ground from the engine block to battery negative post. If things start working, then it's a failed ground.
The only way to know for sure is buy a manual gauge and test it. Hook up the hose with the treaded makes end to the block. Usually located above the oil filter if your under the car. There should be a plug and wire attached to it, that your oil pressure switch. Take that off and attach the manual gauge to it. Turn your car on and let it idle, for like 15mins. Depending on how cold it is outside, and your oil viscosity of your oil, like how thick your oil is. 5w20 normal and 10w30 is thick. You want your oil to warm up so you can get a proper reading, look in car manual for oil pressure specifications on the reading.For example my 95 honda civic says at idle it should read 10psi and 3000 rpms on your tachometer in your the gauge should read 50psi. If all is good it might the gauge in your car. Good luck.
I think that version of the Cherokee needs you to be travelling at less than 3 mph to change your ratios. Try this...
Come to a complete stop. Keep your foot on the brake or apply the park brake. Put the vehicle into neutral. Firmly slide the 4wd lever to the ratio you want. Put it back in gear, as you would normally, and drive. Try to keep the 4wd lever out of the N position.
when you check fuses you must use a continuity tester or a volt meter to verify they are indeed not blown also clean the contacts in the sockets and your turn signal switch may be finished and needs replacement your vehicle is now 17-18 years old by manufacturer date sticker so things fail after almost 20 years there could also be a broken wire on that socket but verify fuses so you can eliminate that cause sometimes they look good but are blown out in the corner at the top ok
Does the vehicle stall? Is this code intermittent (goes away)?
If so, a cheap test, possible fix is the MAP sensor. To be sure, look at the freeze frame data and look at the manifold pressure itself. If manifold pressure suddenly jumps to near atmospheric pressure (i.e. zero vacuum while under part throttle load) replace the sensor.
If the line is bad, pull bad one and go to local parts store and get needed length. Actually, whenever I've had to go that deep, I replace all vacuum lines as they tend to get brittle and crack with age. Replacing all avoids failure down the line. And bulk vacuum line doesn't cost that much. You might consider replacing that T as well.
