No start 6.7L

2017 6.7L, 28k miles,............ NEVER an issue. Left work to come home and the truck just cranks over attempting to start but won't go, multiple attempts too. Had it towed to dealership. Anyone know if this has been a problem with others?

could be many causes, of course. Hopefully yours will be a simple fix

I realize the various reasons of a no start. I am simply wondering if anyone else had this with a '17 and up.

I just heard from the dealership and they said it had/has low fuel pressure. Asked if I gassed up from a different fuel station, etc. Could be moisture in the fuel and or bad sensor. They do have it running like normal but don't want to release it to me and have it happen again until they pin point the source.

Update.......truck did not start the next day. Towed it back to dealer. However, upon being hooked up to the flatbed wrecker, I noticed two wires hanging by the driver frame rail, these two wires I installed to my upfitter switches (last winter), one is for a small back up light and the other is for a back up alarm. I tugged on these and thought, lets try to start it one more time before being towed, it started right up. I drove it to the dealer and it sat there for two days being tested, they cannot duplicate the crank/no start, Its been started tons of times in the last week without failure. I'm wondering if I had a loose upfitter wire rub on something causing these no start symptoms. No codes, no CEL , etc., seems perfectly normal now, but I'll always wonder what happened.

And yet, another update. Had the crank/no start again yesterday, BUT,.........I was able to pull codes for the dealer. They found a defective fuel pump control module and a corroded #4 terminal on the connector. Hopefully I'm done with this nightmare.
