jeep wont start without a jump and cant hold an idle when started
ok so i have a 97 zj 4.0 and when i try to start it the lights dim and it clicks but wont even turn over. i tried starting in neu with no luck, i tried hitting the starter with no luck... im thinking one of three things bad battery(highly unlikely since i have a year old optima yellow top in it) bad alt, or some kinda short/bad ground. i have a jumper pack, and when i connect it to the battery all the lights go back to full strength and she starts right up, but if i dont keep giving it gas it dies... any ideas? i need this for work in the morning tomorrow.... but im thinking i may be screwed lol

This exact thing happened to me about 6 months ago. I also have an Optima Yellow top. I replaced the battery under the Optima 3 year warranty and the Jeep was cranking just fine afterwards. My bet is on your battery.

I would check the connections. it's summer time that the corrosion really builds up there. get a battery terminal cleaning brush, it's like 1.99 at the auto parts store and try cleaning the battery terminals and all the connection. DONT BREATHE close to this when doing so. I would do this first before replacing anything as it can affect not only battery power, but charging of it as well. either way you will need one of these too. I've helped 4 friends out with "dead batteries" this summer and it was just the contacts.

Not an expert, but the bad idle is probably coming from the fact that the battery is dead. now with a new battery or charged battery, the computer has to relearn ur settings. happens to me every time the battery is disconnected.
Something happened to me - the Jeep went into a river, the water got all over the battery. The charge system would not charge or had problems charging - low voltage. I could figure what was going on - cleaned the top of the battery with baking soda, the Jeep starting charging 14+V. Before I cleaned the top of the battery, it looked clean but must have had some minerals from the river there. Maybe be the issue just some information.
