that happened to me when it was new....i got it started it but was idling rough.....I let it sit running for a bit and eventually it went back to normal.....i never figured out what it was and it never happened again.

 

Check your battery connections, clean and tighten them as needed.

 

?
Try disconnecting your negative battery cable for a few minutes and then reconnect; try to start the engine again.
x2 on opening the hood and trying to dry it out... maybe use a shop vac set to "blow" to help it along?

If that doesn't work, I'd use the compimentary warranty tow service and haul it to the dealer.

 

Before you start it make sure your foot is on the brake and then take the shifter and shift it to neutral and shake it around, then put it back it park. This always does the trick for me, good luck.

 

thats the best thing to do is let it sit and dry out
with all the eletronics / sencors ect, ect something got wet and the other thing is defently disconnect the battery until it its dry if water got in the fuse box that can be bad with power running through it .......

off the topic so its rainning back home? we are enjoying the HOT ASS sun in arizona

 

Thanks for the advice everybody, really appreciated all the suggestions! So the only thing I was able to get going was the complimentary tow from Chrysler roadside assistance lol

 

Hahaha must be nice!!! Yeah it was just enough rain to keep the grass green and provide a JK Newbie with a quick lesson in fording lol

Next mod = SNORKEL!!!

 

Yup I agree, take off all of the plug wires and distributor cap (the JK has one right? hmm) and let everything dry out. I used to have that happen on my XJ.

 

Subtract the water incident and I had Ozp's

 

Subtract the water incident and I had OP's exact symptoms a few weeks ago. Disco battery fixed it.
