22 Ram 2500 6.7 diesel

[Befuddled]

I parked my truck on the side of my house for two weeks, went to start it, cranked just fine, no start.
Def is full and so is the fuel tank.
only code I had had a under boost, but that never kept it from starting and running. Sometimes it would clear itself and the idiot light would go off. I did pop the hood and discover something chewed up my battery blanket on the passenger side but have not seen any other damage. I going to look it over carefully this week end. Just curious is an under boost issues could make it not start when it’s warm outside, during winter months when it was cold, it always fired right off. Has brand new batteries.

Are you running an aftermarket fuel filter?

Likely a wire chewed in two somewhere. Check the wire that goes to the back of the HPFP. Also listen to see if you can hear the lift pump running.
I’ve got a half dozen cats that hang out at my house and have never had a varmint problem. They catch snakes too.

If the under boost is caused from a substantial air leak the slight potential is there for a no start, but not really likely as the engine usually idles at a vacuum.

Check the wiring under the forward fuze box . I had a mouse get in there and chew some wires and it wouldn't start . IFF you can put a dawn to dusk spot light under one end of your truck . It is really effective at keeping nocturnal out . They don’t like light !
