You're going to need something to read IPR percentage, and ICP, FICM volts etc. You're pretty much in the dark with these engines without being able to read those values

It can take a lot of cranking to get oil back through the HPO system after changing the ICP, IPR, and pump. I'd put a charger on the batteries and try some more.
If you want to speed up the process a little, pull the oil filter and standpipe out of the housing and pour a quart of oil in the hole. This will fill the HPO resivour and give you a little head start. The standpipe has three Torx screws at the base, only the one at the rear position needs to come out. Loosen the other two just a bit and twist to remove. It's plastic and can break if you get heavy handed with it.

There is a no start thread in the tech folder also, it has some good info on some things to check.

And you shouldn't need to bleed the fuel, I've had mine apart many times and never bled it.

Unless the problem is real obvious it hard to work on these trucks without some type of diag device.

I put this up for basic info: https://www.ford-trucks.com/forums/1...eral-info.html
Some of the smartphone apps work surprisingly well.

If you have a check engine light on, most of the auto parts stores will scan for fault codes for free. It's also possible to have a code set without the light being on. Might get you on the right track.

I think there is a low power thread in the Tech folder also. Might be something in there that ring a bell for you.

If you just want to take a swing at it, new fuel filters is a good place to start.
