I have a 98 Cherokee sport and as I was driving down the driveway today she died and won't start back up again. In fact, she wont even crank. I know my battery has enough charge in it and is getting a good connection, when i turn the key all I hear is a faint click from the passenger side. Also, the parking brake light on the dash comes on. I just drover her the other day with no problems!! Please help!!

 

Not sure about that parking brake light.
But regarding the no crank-no start: if it's an auto, it can be the Neutral Safety Switch (NSS) playing up. Wiggle the shifter, or go through the gears a few times and try again. Have you tried starting in Neutral?

The battery might hold some volts, butcan still be subpar to start. Recharge and try again, or better: have it load tested.
Make sure ALL your connections in the starter circuit are clean and tight. Including the grounds.
It sounds very electrical.

 

Mine recently had an issue just like this. I had an oil leak and the oil was building up on the starter cables causing it to not get good connection. Try wiggling the starter wires a few times and then try to crank it. Better yet, if you have some electrical parts cleaner on hand, go ahead and get all the gunk off the starter and then see if it will crank.

Also, as the previous person said, check your NSS. If you put it in reverse and your reverse lights dont come on then there is a possibility that it is your NSS.
