WARNING: This page is about a different variant/trim than selected.
P00C6 - FUEL RAIL PRESSURE TOO LOW - ENGINE CRANKING

Description:  The high pressure fuel system must reach a minimum pressure threshold before the engine can be started. This DTC sets if the high pressure fuel system cannot achieve this threshold within certain time and crankshaft rotation limits; the PCM attempts to start the engine at fuel pump assembly pressure.
Possible Causes: 
  • Fuel filter plugged or dirty
  • Fuel supply line restricted
  • Damaged fuel pump module
  • Damaged fuel injection pump
Diagnostic Aids:  Diagnose any fuel rail pressure (FRP) and FVR circuit DTCs first.
