2005 6.0L stalls all the time, hard starting also

[caissiel]

Checked everything on this truck, FiCM 48V, ICP 685 Idling, EGR was stuck at zero but bounced back after hard reving, Cleaned EGR Valve and it was not very dirty. Turbo ran up to 32PSI.

I am leaning toward the Campshaft sensor, or the STC fitting.

This a friend's truck and he has been trying to get rid of it, and I am try to encourage him to keep it, for the value he is getting in trade is very low.

You have good values so far but what are they when it off and trying to start?

[caissiel]

They were read when the truck was not starting and after it started the EGR was stuck on zero and after reving it to 3000RPM for a bit it went to normal. That was my test and now he has the truck and driving it like that, mad as h..l. I would like to help him, I changed the FICM last fall, and the EOT has been good, with ELC-1 Flush. Actually if I floored it it stalls on rev-down. Compared it to mine, his Turbo Goes higher but I felt that the ICP was low I never saw 1000PSI. He has an Air Raid filter setup, and there is an air filter message in the dash that I can't cancel, and no codes.

You said it was running for these tests. Take readings of ICP actual and desired as well as IPR % actual and desired while cranking. what all does your friend have done to the truck we need more info on the vehicle before we can really help. Also what are you using to get these readings?

the air filter message on his dash is probably from the filter minder, my minder kicked rocks a couple months ago and i got the message, un-plugged the wires running to it and no more "check air filter" message.

I will be checking the truck again on thursday and report back. Thanks for the previous answers. We are checking prices for CMP and IPR, I have a scangauge II programed for my 6.0L.

Just drove the truck home.

Started right up with pressure on accelarator, but stalls all of a sudden at Idle only.

Some readings on the scangauge.
Idling: ICP 585, IPR 21.5 PID list desired as 625/24
Idling at 1100 RPM: ICP 680 IPR 23 PID list desired as 1400-1450/40.60
No codes

Running down the road at 50MPH, RPM 2000, ICP 2000-2500,

My Truck ICP is 940 at idle or just after start, I have been comparing his reading to mine and they are definitly different specialy ICP readings but it starts good

Did not check the load but the trucks felt it was out of power. But the rims get hot from brake rub on the disks.
