What did you do for the EGR delete? Did you just weld it up?
You also will pull a P401 code for low airflow to the EGR
I have pulled everything apart on mine several times, besides pulling the heads. There are alot of variables on the 6.0, however how did it run when it started? Was it running rough?
Have you done these steps:
Check the clips on the injectors, make sure they are installed and tight.
How long has it been sitting? try draining the water seperator and add fresh fuel.
Look for fuel leaks under the filter assembly for the under hood filter.
Look under the turbo where the oil tube goes from the turbo to the cooler and check for leaks. Those hardlines can be a pita if you don't lube them.
Make sure all your connections are tight on the FICM
Also what year is your truck? Each year of the 6.0 had different and common issues.
