Cranks for 5 seconds

I just bought this truck, it is a 06 f350 6.0 The truck runs great but it cranks for 5 seconds before it starts whether its hot or cold. Truck has just over 200k on it. I do have access to a scanner, what should I be looking for? From what I've been reading it could be a HPOP, STC fitting, standpipe and dummy plugs, ect.. Anyway to narrow it down, I really don't want to replace the hpop at 700 if I don't need it.

Re: Cranks for 5 seconds

More then likely, its just a leak. Watch ICP voltage and IPR duty cycle.

Re: Cranks for 5 seconds

Watch the ICP and see how long it takes to get up to at least 500psi. (the point at which the injectors will be commanded on). If it takes the 5 seconds for the ICP to climb, that is your problem. It could be a leak in the high pressure system or something as simple as the wrong filter/cap letting the oil drain back.

In general the HPOP is pretty reliable in these years. Much more likely to be a leak.
If it were mine, I'd pull the oil filter and cap and make sure they are the correct ones. (for example, Wix makes a taller cap that only works with their slightly taller filter. If someone put a standard filter under a wix cap, it won't close off the drain in the bottom of the housing and the oil will drain back every time)

Re: Cranks for 5 seconds

Can you get a datalog? Watch ICP voltage, not actual pressure. Pressures lie, voltage doesn't. Tell us what it does while cranking, and how quick it gets to .6 volts

Re: Cranks for 5 seconds

ICP voltage shows .24 for 4-5 seconds and at the same time it moves to 1.14 volt it starts. As soon as it starts actual pressure and desired pressure read 900psi or so. I'm not seeing the pressure move until its already started though either so I'm not sure if my snap on scanner isn't reading while cranking or if that's just what it's doing?

Re: Cranks for 5 seconds

What does the IPR duty cycle do while cranking?

Re: Cranks for 5 seconds

I see injector pressure reg % reads 15 key on and cranking and then jumps to 70 when it starts
