The fuel pump is mechanical for 2250 was / is there a need for any type of calibration update?
Also i did run a Cylinder Cut out Test - Passed
Attempted to Run Injector Perf Test - Immediately fell on its faced and died when the ECM shot fuel to it.


What it is the exact code(s)?

Just make sure your ecm calibration is up to date (latest one from cummins) and that it matches your engine and truck exactly. After that, Start checking the drain lines, there is a blockage or restriction in the drain somewhere.

You also did not mention what make/model truck it is. Some Volvo trucks have been showing some sensitivity to the excess drain line pressure codes.
