Been having some issues with my f-250 and we keep hitting walls. Started with batteries not holding a charge and dying on me twice while out. Charged the batteries then checked fuses for parasitic draw, nothing. After, truck would crank but not start so called a mobile mechanic and was told FICM and fuel injector control pressure sensor, replaced both and still just crank and no start. We’ve got no clue what could be causing this now. I’ll attach the mechanics scanner finds that were taken before replacing the sensor and FICM. help lol

also does anyone happen to know what size adapter is needed for a fuel pressure kit to see if my fuel pump is good or bad?

 

Do you have a voltage modified FICM?
Is your EGR valve unplugged?
The codes indicate a bad GPCM.

What is your ICP sensor voltage output at KOEO and when cranking?

The test port on front of Secondary Fuel Filter housing is M12x1.5

 

Hi Bismic,
Hope you are enjoying a holiday.

Not that familiar with 6.4 & 6.0, mostly Cummins, thanks for your help and participation.

 

My pleasure Hanky! I don't check here as often as I should.

Happy Easter to you also.
