08' 6.7L last few days my trucks been getting harder and harder to start... Today it wouldnt start at all. It sortive clicks, sounds like the starters engaging but wont spin. Is it just the single didgit weather or something going bad. Yes the batteries are fully charged. Any answers would be appreciated.
Does sound like your batteries though, or maybe a lose connection, check your battery cables and make sure there clean and connected good, if that aint the problem then more then likely your starter went bad and needs replaced. And how sure are you the batteries are charged, if it was harder and harder to start, thats a good sign of your batteries being weaker and weaker.
Mine when i first start it in the morning clicks behind the dash and usually gives me a p2509, after it warms up and i drive into town and i shut it off and crank it while its still warm the engine light goes away..i think mines something with a weak batterie..your starter might be shot
