My 1996 jeep grand cherokee died last night and i mean DIED. it is sitting in a parking lot. I got a jump to help turn it on and as soon as i took my foot off the gas it died. I did this numerous times and it still is sitting there. If i take my foot off the gas it just dies and needs to be jumped again.

I would have a load test done on the battery as there is a dead cell evident from the number of jump starts you need. Have an auto electrician test the alternator for charge rate and out put. check drive belt condition and tension.

Have throttle body cleaned and "minimum air rate" adjusted. Computer looses learned memory when battery is disconnected and has to start over again.

Look into the crank sensor or an ecu that needs repairing. Those two, being bad, will cause a no spark condition in your jeep.

have you tried to replace your fuel injectors or your spark plugsif not try checking your fuel injectors electric socketit couid be loose

that's because the battery was too dead to maintain operation you need 9 volts at the battery for the computer to run the injectors,the alternator was dumping all it could into the battery to revive it.and at idle it just wasn't enough. seems like you have a bad fan relay and a very dead battery. hope this helps you.

Have the alternator and the battery tested as one if not both items may have gone bad.

the alternater may need exciting try reving it pretty hard to excite it

this sounds like crankshaft position sensor, my Cherokee was ding same thing it ended up being crank shaft position sensor. this part costs about $50 and is easy to install.

The codes will only lead the technician in the right direction to fix whatever part has failed, it won't be the fix, just wanted to make sure you understand that.

have the alternator regulator and diodes tested. sometimes when the regulators fail they allow ac voltage to go to the battery. ac voltage doesn't charge the battery properly (causes it to deep cycle and shortens its life) and causes all sorts of funny problems with the car. also make sure the battery is secured properly, vibration isn't good for them at all.
