Have you done the fuel pressure regulator?(Blue spring upgrade) and are you using a mechanical fuel pressure gauge hooked up to filter housing? Fuel pressure below 45 psi causes injector damage
HELP!!!HELP!!!HELP!!! 2005 ford 6.0
HELP!!!HELP!!!HELP!!!2005 Ford 6.0 truck will run smooth for as long as you let it idle, once you start to go down the road and get it under a load it will die out like its starving for fuel and will not restart. FICM volts is 48 builds up over 500. fuel pressure is at 60 psi and drops down to 45 while cranking, no codes what so ever.
update:
This morning when i got here i tried to crank it up again. it crunk up for just a few seconds and then died, i was able to pull up the power balance and the truck was running rough and it showed cylinder#1 was dropped and cylinder #3 was also low. again icp was building up to 600 psi then maxing out. i decided to unplug the ICP sensor and watch the ipr Duty cycle. with the ICP plugged in it was around 56% when i unplugged the ICP sensor the IPR maxed out at 69% generally i have seen them max out at 89 i dont want to just throw parts at it, any help would be nice. just never had an ipr cause this type of issue

Only other thing to check would be ICP sensor volts when cranking.
"crunk"?...update:

Is this conjugation diesel-specific?
It rather does make sense; drink, drank, drunk...crank, crunk. I like it.
yes i done the blue spring upgrade, and yes i used a mechanical fuel gauge now it stays around 55-60 psi while cranking. friday i ended up getting it running and drove it 7 miles got back to the shop to charge the a/c back up and now it has a hot no start. got it crunk this morning ran a contribution test and now it has completely dropped #6 injector. electrically it is working when you run the buzz test so now im waiting on an injectorHave you done the fuel pressure regulator?(Blue spring upgrade) and are you using a mechanical fuel pressure gauge hooked up to filter housing?
