Long Crank Cycle after Fuel Filters Replaced

[RBax]

Hello All! Just picked my 2021 2500CTD up from the dealer after its first oil change, tire rotation and replacement of both fuel filters. Upon initial start-up the engine crank considerably longer than it did prior to the service. As a test, shut it off at a traffic light and re-started as normal but if sits for a period of time the crank cycle is longer than previous.

Thoughts?

Thanks!

It's just air in the system, it will work its way out with time

when i'm finished swapping in new fuel filters i like to cycle the key 4-5 times without starting the truck and it seems to start right up every time. I've never had a long crank situation like you're describing. May want to give it a try, can't imagine it's gonna hurt anything. Good luck.
