Message: [QUOTE="webb06, post: 1552667, member: 7680"] Seeking any advice or help with this truck. Truck has 262k miles. Customer just bought it from another friend who is a car dealer. Previous guy bought it in December and it’s done this since he’s owned it. Extended crank (4-5 seconds) at all times but will always start. Push button start. If you immediately shut it off and restart within 1 second it’ll start as a normal 6.7 does. If you wait 2 seconds (literally) it will long crank and fire up. New owner installed tune and dlete hoping it might fix it. No luck. Truck drives 100% normal and will hold rail pressure under WOT. Low pressure system seems fine. Will build 60psi. Cycle ignition on and off before attempting start is no help. I can watch on IDS and it appears rail pressure is slow to build. Seems to stall around 1500psi then go ahead and build to 5000 and start. So far I’ve replaced the driver side fuel rail, including pcv and rail pressure sensor. Removed vcv and it’s clean. Swapped anyway no help. Swapped crank position sensor off of my personal truck. Reset crank sensor and all high pressure resets available on IDS. Tomorrow I plan to block of injectors one at a time to see if one is leaking off. If not that then I plan to swap the injection pump. Sent from my iPhone using Tapatalk [/QUOTE]
