Hard cranking
Hey everyone, I recently purchased f250 2017 6.2 97k km.I Used to have occasional long cranks, only when warm which is common for fuel pump. Recently the long crank went away, but now the truck stumbles or misfires briefly while cranking - it almost dies,then catches and runs fine. This happens on both warm and cold starts now. It’s never failed to start, just struggles
So far I replaced the purge valve, battery brand new , cycling the key before start doesn’t help, no check engine light, no codes.
What could it be?
Any advice on where to start testing would be appreciated.
Also I attached a video below
