reduced engine power
i have the codes
p0087 fuel rail pressure to low
p0089 fuel pressure regulator performance
08 ss turbo
car has 57000 miles i think its the high pressure fuel pump within 8 miles of driving homei started hearing a little rattle. i got home n had someone rev it up while i poked around with a stethascope n it seems to be the high pressure pump. the usual ticking is extremely loud. are these symptoms synonymous with needing to replace the pump?
thx to anyone that helps i gotta new job n gotta have my car for it

First check the wiring I reference in this thread

If that's no the issue then your high pressure pump is likely shot.

Oh man.. It seems everyone encounters this problem... Same codes that I had last month. I first replaced the HPFP then it worked fine for about two weeks then the same stuff happened again.. So I then changed the pump in the tank and the car runs great now!! Been almost a good month. I totally just jinxed it though now

something right where the hpfp is is rattling pretty bad. i have 2 thoughts. either the spring broke or the roller broke. both are not good.. i wont know til my day off on saturday but il post back n hopefully neither the spring or roller broke but those r the only 2 mechanical parts on it as far as i know n whatevers fucked up it rattles more with more rpms... idk if u guys have any other thoughts lmk its driving me crazy.
