*911* 7.3L not starting.

Helping a buddy work on his uncle's 2000 7.3l. Truck is not starting unless plugged in for a couple hours. And even then it barely starts. WILL NOT start cold in 50* weather. And we are not getting any smoke while motor is turning over.

Glow plugs have been replaced. Valve cover gaskets and uvch's have been replaced. ICP has been replaced. IDM was switched out with good working IDM, no change.

Batteries are good, and have jump box has been hooked up also.

Motor is turning over fast, just not starting.

HPOP is full of oil. Fuel bowl is full as well, and when emptied fills up as it should.

We are now stumped as to why its not starting.

Y'all got any ideas?

You might need a new ignition switch. Do all your lights inside and everything work?

Yes big time for at least 10 min. But will only start when plugged in for a few hours. And even then it takes it a bit to get started
