I have a 2001 f250 7.3, auto 4x4 200k miles. the other day I started it getting ready to go to work and it idled for approx 5 min the sputtered and quit. I can restart the truck but only if I have the pedal to the floor. things that I have already done...new pedal, new icp sensor, new cps, I have 3/4 tank of fuel, cracked the fuel bowl lid and turned the ignition on and I am pumping fuel to that point. now Im kinda stuc. please help!!!!

I would hook up a monitoring device such as Torque Pro app to see what the HPOP is doing because that's where the problem most likely lies ... check what the ICP is while its idling and cranking since you probably cant get a WOT reading.. also check the IPR percentages

So my truck does not idle, it will only start and run with the pedal to the floor. And it runs horrible at that. Things that I have done...new pedal, new icp sensor, new cps, I have 3/4 tank of fuel, cracked the fuel bowl lid and turned the ignition on and I am pumping fuel to that point. I have replaced the fuel pressure regulator, inspected the undercover harness, hpop oil level is full,

What did the IPR read cause you had plenty of cranking ICP... That seems like one of the only things you haven't looked at
