JK 2010 won't crank

My RHD jeep wrangler sometimes won't crank ! any help what can it be ?

 

Welcome @jrgrajales ...start with the basics before anything else. How old is the battery? Starts with a jump? How old is the problem? Get the battery load tested at auto parts stores like advance/autozone. While you're there they should be able to check the charging system. Sometimes it could simply be connections, bad grounds or the starter. But one step at a time.

 

battery is new, the starter makes no sound, it is as if no electricity comes to it!

 

Based off your description (no sound) guess its like trying to start in gear. Just a few more questions: Intermittent no start? Jump start-able? Have you tried to wiggle the AT shifter into PARK or try to start in NEUTRAL?

 

Still there - hello -
Can we find out a little more- automatic or manual?
Can OP do simple electrical tests with a test light?
