Longer than normal crank times

[Chaddison]

On my 2020 CTD I have noticed recently longer crank times if I just hold brake and hit button vs cycle button to run, let it sit for 10 seconds then button again off, then brake and button. The difference is about 5 seconds of turning over to crank on almost immediately. I’m in Texas so have only had it hold the crank to warm a few times but even then it’s a long crank cycle.
I have looked and have first version CP4 with no large dimple even though it’s a July 2020 build and had 2 previous CP4 F250’s, one had a blown CP4 at 25,000. The reason this concerns me is that the F250 did the long cranks for about a week before it took a dive.
I have a call into local dealer to run a check on it but it’s at least a week out, anyone else notice this on there CTD’s 2020 or even more on the 21 with CP3?
I may just be overthinking it I haven’t had a ram since 2005 and all of those long cranked vs Ford with the lift pumps instantaneous.

I am a little confused by what you mean by long crank. If the truck needs to preheat it wont crank until its ready. If your saying that once you push the button and its delayed slightly before it cranks over it that is normal. If its struggling to crank over it may be a bad battery.

I’m sorry it’s weird to explain. Not a heating cycle how many times it has to turn the engine over to fire up. Like this morning it took about 6 seconds of spinning over before it fired up, like old days with no lift pump in tank. But yesterday morning I did the ignition on cycle then off then back on and it cranks up within a few engine revolutions like 1 second.

it could be a fuel leak issue I guess not keeping fuel to the CP4 primed so it takes it that much to get it to the engine. Just curious if others have noticed the same results on engine rolling over to actually firing up.
