2010 GL350 don't crank
 

Greetings
I recently purcgased a 2010 GL350 (BlueTEC) with 150k miles on it. The car was running fine, I parked and now do not crank. The battery is brand new, 2 months old. I tried to recharged the battery, by the way was full of charge.
I did the basic troubleshoot, the starter and the relay are fine.

Any idea about next step?

Thanks in advance
