I’m sorry I don’t have the part number anymore but the dealership called the the higher pressure pump bucket. But the light came back on today with the same codes. The bucket that I previously replaced is getting damaged again. The cam that actuates the high pressure pump is worn out and keeps damaging the so call bucket. Now I need to replace the eccentric cam lobe and timing chain cover. I found this post today
Very helpful, I wished I would had found this before because It would had saved me a lot of money and time.

Infiniti dealer states that now I need an complete engine. Timing chain broke and bent the valves. Known issue with this vehicle model and year but Infiniti corporate does not want to cover it because my VIN number does not fall within the open recall Vehicles. And the nightmare continues... this went to hell really fast.
