Fuel Injector: Removal

WARNING: This page is about a different car, the 2008 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Do not allow fuel to spray when removing the pipe between the high pressure side fuel pump and the fuel injector. The fuel in the pipe is highly pressurized.
  1. DISCHARGE FUEL SYSTEM PRESSURE 
    CAUTION:
    • The "DISCHARGE FUEL SYSTEM PRESSURE" procedures must be performed before disconnecting any part of the fuel system.
    • After performing the "DISCHARGE FUEL SYSTEM PRESSURE" procedures, pressure will remain in the fuel line. When disconnecting the fuel line, place a cloth or equivalent over fittings to reduce the risk of fuel spray.
    1. Remove the console box (see appropriate step(s) under REMOVAL ).

      NOTE:
      • Check for foreign matter in the fuel tube around the fuel tube's connector. Clean it if necessary. Foreign matter can affect the O-ring's ability to seal the connector and fuel main pipe.
      • Do not use any tools to separate the connector and pipe.
      • Do not forcefully bend or twist the hose.
      • Keep the connector and pipe free from foreign matter.
