Hi all
Have a 2016 LML will not start. Drove fine and shut it off and now will not crank.
Just hear a click.
Some background:
Truck is stock with 140000kms. Had a slow crank/start issue for the last little while which I knew was a bad battery. Tired to boost it and still wont crank.
Replaced both batteries and checked relays. No change.
Had two codes P2510 and P262B. Cleared and P262B returned.
Everything points to ECM buggered but just wanted to check your guys thoughts as well.
Thanks

Try removing the negative battery cable for both batteries overnight. Maybe even put a charger on them also. In the morning reconnect and see if you still have the problem.

Update: Ended up being the starter. Running again.
