When the truck Sits for a half a day. When i go to start it, i turn the key to start and nothing happens. Nothing at all. I got to lock the door and unlock a couple of time to finally get it to crank. Sometimes even off the ford app, it wont start. Could it be a faulty wire?

 

Probably a bad connection/ ground.Could be many other things too. Being a 2019, I would assume you are still under warranty and I would let the dealer address it.
