I have an 03 duramax. I keep tripping a P0088 code and a P0380 ( I forgot to write that one down but I think that was what it was) codes. The P0088 is for a high pres. fuel rail the other is something to do with the glow plugs. I think one comes up becuase of the high pressure one. Any how from the searching I have done everything seems to lead to the Fuel rail pressure regulator is strating to go bad. I am wondering how hard of a job this is to change out myself. I am moderately mechanically inclined. However I am haveing trouble finding a schematic on where this is located and what the best way to go about changeing it out is. Thanks for any help. Greg
