Ive been suffering through similar issues of turning over but not starting. sure enough it was fuse#27 being fried. pretty burnt up. i changed it out and it fires right up. kinda wondering why this thing burned out though. this happened at 53k miles/2013 screw

Nothing on any of the switches. Tune's been off the truck for 6 months as well.
