First of all just want to say thanks to all the great guys on this site. I have been using it for years now but never made account, because I have always found my info on here with out asking a question..... till now!

Here we go
2009 f350 4x4 with 135,000km

when I come out in the morning to start the truck it fires up no problem, but after the truck warms up it has a extended crank for up to 5 seconds. But if the truck cools down for about 2hrs it will start up with normal cranking

things I have done

timing chain
variable timing slack adjusters
timing chain and sprocket's
spark plugs
fuel driver unit
air filter
fuel filter
mass air flow sensor


there is no codes, the truck runs great fuel economy sucks but that is normal lol.

I have taken it to Ford had them scan it they can come back with nothing

any help would be great
