Update-not fixed Fitted new relay as only £10,checked/tested as advised, started ok and run for awhile,Now have codes p1517 coded security,p1112 fuel rail pressure,p1138 fuel pressure regulator. Cleared all again and just got p1138. Just thinking have i fitted a faulty in tank pump as all else was ok till the old unit siezed? Will try to measure fuel pressures,am i missing anything else? Thanks Tony
