2019 RST model twice the truck crack over but will not fire. Both time after multiple time trying it starts. One of the times I waited until all light went off in dash. Then it started. It like it has to reset the computer? Has anyone experienced this? The dealer is scratching there head.

 

The problem is that there are so many sensors, and electronics involved, it could be a number of things. Easiest of all is the battery. Next time it does this try a jump and see what happens. Or it could be a loose ground. Diagnosing from a computer is not the greatest form of checking.

 

Try another dealer. This is a warranty thing.

 

It's not the battery. The truck crank until you stop it. Had it at the dealer today. They checked a relay. Time will tell.
