I shut my 2015 6.2 truck off at the bank drive through. After about 5 mins I tried to start it and it turned over but wouldn't start. I turned the key off and tried again and it started right up. I'm worried it might do it again and not start. Anyone have an idea of what would cause this?

 

It’s run by a computer...just a momentary glitch maybe? If you don’t have secondary symptoms and it’s not repeatable I wouldn’t worry too much.

 

I've started it at least 20 times and it runs fine. I'm hoping for a glitch.

 

clean the battery terminals... but most likely a computer glitch..

computers dislike loose/dirty battery terminals. BIG TIME.

 

I'm going to clean terminals tomorrow. Disconnecting the battery couldn't hurt.

 

There was a thread or two about the fuel pump module being in a vulnerable place subject to corrosion and causing issues.

 

I'll keep that in mind. Cleaned battery terminals before work. Truck seems fine.
