Dead 6.0 Dave C'ville

[Dave C'ville]

Hello,
This is my first visit. I have an '03 F-350 6.0 that slowed way down , would not speed up no matter how much pedal. I thought it might be exhaust related, seperated the exhaust before the converter, that made no difference.Then it stopped. We ran a code on it and these are the results.[LIST]
Code P0401 (replaced the EGR); P0603; P1000; P132B; P2290.
It would start and idle, after replacing the EGR it would not come up on speed to a full idle. We sampled the fuel and took to a lab for tests. Fuel is good. I changed the fuel filters. I changed oil and filters. We tested the fuel pressure it was 6o Lbs. We took piping loose and turbo spins freely. It will not start.
Coould it be the Hi pressure oil pump? OR the turbo?
HELP,
Dave C'ville
