HI. Thanks for using JA! I will try and help you out.

When you say "deliver pump". Are you talking about the HEUI pump? If so, sometimes when these pumps fail, they can release metal debris into the high pressure oil system that feeds oil to the injectors. If there is metal in the system, the injectors may be damaged.

IS the check engine light on? DO you have any way to read the ECM and check for diagnostic codes?
