After sitting for a couple of days battery dies and has to be jumpped

remove your boot & glove box light to check if they are the problem. let it sit without the globes in for couple days then try.

You never jump a dead battery
That is an unsafe act and could
result in an explosion

You must charge any battery fully,
to start any diagnostic proceedure

You never remove either battery cables,
while a vehicle is running,another practice
that will bite you sooner than later

It sounds as though the battery is not
capable of taking a charge and offers
too much resistance to run the car hooked up

yes replace battery the computer cant work on a dead battery ..

CHECK FUEL PRESSURE....BAD ALTERNATOR WOULD CAUSE THE BATTERY LIGHT TO COME ON.

its not a problem all cars all batteries do that if they sit after couple day min especailly long period of time you will always need a jump to get those cells in battery alive and active once car starts its good should have no problems

if you have a multi meter disconnect positve battery terminal and put red wire to battery and black to battery cable put multi meter on resistance should be 0.005 or less if more then check for things that may be plugged in to cig lighter etc turn door lights off etc dont turn key on any more than 0.005 will drain battery

Hi!
Start by charging the battery completely. Then, start your car and while running, remove the NEGATIVE battery cable from the battery. If the car dies, your alternator is bad. If it keeps running, reinstall the battery cable and turn the car off. Check for something that's on that would drain your battery like a light in the trunk, glove box, etc. that wont shut off.

Hi

Sounds like your battery, have you had it heavy discharge tested ?

Get the alternator charging rate tested if battery tests OK.

Good Luck !

Please give a FixYa rating !

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.
