From all to searching i got i would seafoam your fuel system first, if still persist going from the least expensive to most... egr vacuum soleniod, egr valve, dpfe (egr vacuum sensor), maf sensor, and then injectors reset your computer after each fix by disconnecting your negative terminal on your battery for 15min or so. Check your prices at you parts store as i have not looked up the fuel pump but should not be your problem. I have the same issue and will figure it out and repost here. If going through the process of doing the least expensive first at least you will have known good parts to get you through.
