• Sub-steps:
  1. Remove the engine cover (if applicable) to access the fuel rail.
  2. Carefully disconnect the fuel injector electrical connectors.
  3. Remove the fuel rail bolts and lift the rail with the injectors attached.
  4. Inspect the O-rings of the injectors; replace if worn or damaged.
  5. Reinstall the fuel rail and reconnect the electrical connectors.
