RE: Fuel rail pressure
Throwing any codes? Have you checked the fuel pump? Has the fuel pump had any maintenance? How many miles on the truck?

RE: Fuel rail pressure
If its throwing fuel rail pressure faults or any fuel related faults on a cm2250 which is what im guessing you have being 2012. replace/rebuild the pump immediately. the fuel pumps in the 2250 and 2350s can an will destroy the entire engine if they let loose

from what ive seen posting around here a common rebuild mileage is 350-400k miles to reduce the risk of a 30-40k boat anchor.
