Ford 7.3L Power Stroke (1999-2003) :: 2001 - No Codes - Crank But No Start?

I purchased this unit, non running, was told the HPOP was bad, after going through the unit top to bottom, Im stumped, below is a list of items serviced and or replaced with OEM parts.

0. changed oil and oil filter
1. Terminator 500 Hpop
2. New ICP
3. New HPOP lines.
4. New starter and solenoid
5. Serviced Turbo (rebuilt with new parts and WW wheel)
6. Serviced Injectors (shimmed) all test good.
7. new pass and driver harness, UVHC replaced, glow plugs replaced.
8. new heavy duty GPR
9. Tested IDM no issues.
10. Hutch mod on tank (re-circulator was stopped up) deleted it, added inline filter.
11. serviced fuel bowl with new parts, upgraded parts on fuel bowl new blow off valve, new drain valve, tested heater all good no blown fuses.
12 replaced faulty fuel pump

Might be leaving something out of this list, the truck has run but only for very short periods of time, (hence the dropping of the fuel tank)

fuel pressure at 70 psi, some white smoke, connected to on board computer, checked every conceivable possibility No DTC codes, my gut tells me it has to be fuel related but at this point I just have run out of things to check.

I have tested everything with a fluke multimeter, including the IDM and all the circuits to the 42 as well as all the way to the injectors and glow plugs and find nothing wrong all tests yield valid readings,

There may be other information available but my after market scanner does not show any issue, KOEO buzz test results good.

The three times I have had this unit running it was dumping lots of white smoke, however after the last round of dropping the fuel tank and replacing the fuel pump the white smoke has dropped to a minimum, but cannot get the truck to run, cranks, wants to start, almost starts, got it up to 800 RPM last try but just will not go beyond that point.

I cannot find anything wrong, must be something I am either missing or its something my cheap scanner can't pick up on.
