Re: Jeep Wont Start
If you have a multimeter i would suggest to measure the battery voltage first. A fully loaded battery has 12.7 V (half an hour after engine off or putting it on an external charger.) When it is around 12.2V its almost fully discharged. This is just a simple check of the battery which you can do at home, but a battery load test tells more about the state of the battery.
Sometimes dirty battery poles can give a problem like yours, so check them and when necessary remove the battery connections and clean them well. The problem could be with the alternator as well, but it needs to be tested first to know for sure.
Oh, and by the way, your jeep is a WJ.
