2014 with factory remote start. It was working fine but now the horn just beeps once and the lights flash but the truck does note start. I pulled the negative battery connection to see if it would reset but that did not work. Is there a fuse or relay that I can check? I have also went threw the menus on the screen. It's set to 10 minutes run time.
Thanks in advance.

 

Try your 2nd key fob to see if it starts, mine did it 1 time and has never done it again since i switched fobs. Maybe a weak battery?

 

A thought here...How much gas is in the tank? They won't (remote) start if the tank is near-empty. A safety precaution to keep you from starting and running the vehicle with no one in it to see the low fuel warning messages.

 

Any luck tracking down the cause of this issue, ozarka? If not, it might be time to get your truck into the hands of your dealer. How many miles are on it?
