low fuel rail press 559 code

I think as far as cummins is concerned they will want you to by a new fuel pump at $4,000.00 bucks, try other checks first but I had the same issue where plunger would not return and it did not run right ...I pulled the barrels and replace the crush washers and it worked but I was doing all the things they tell you not to. 29,000 does not seem low ...if I remember right its from 9000 to 35,000?
