Ok I have a 08/99 F-350 Super duty with 7.3L it died when driving down the road pulled over hit the key and It fired up got it home and went to start next day will not start only crank over. Things that have been checked are as follows

No Codes at all have shown up in the computer.
HPOP is good on oil in the Res.
Motor oil is full.
WTS light is coming on.
Good hot batteries.

ICP sensor- Replaced
Cam Sensor - Replaced
IPR - Replaced / Scan tool showing 15% / 12V going to plug verified/ Brass nut is tight.
Lift Pump - Checked / good working order
HPOP - Snap on scan tool Ethos showing up to 2,250 psi on InjCtrlPr(PSI) when cranking over in live Data for 12 sec.
IDM- Put in one off another truck that is good and did not change anything.
Checked fuses and relays.

Hopefully someone can shed some light on something I have over looked or could check?

Ok I will run a buzz test check the bowl heater and recheck fuses first thing on Wed morning and get back with the details.

No smoke when cranking over.

I have looked over the wiring going into the valve covers and they seem to be good and no wires exposed
Ok so I went to do a buzz test (KOEO) self test on snap on scan tool ethos. I can hear the fuel pump kick on but that's it no buzzing from injectors.
If the pcm was bad then it would not communicate with a scan tool Right?
