Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Inspect and Replace Fuel Filler Cap
  • Remove the fuel filler cap and inspect for damage.
  • If damaged, replace with a new fuel filler cap (ensure it's the correct part for the XC60).
3. Fuel Pressure Check
  • Connect the fuel pressure gauge to the fuel rail.
  • Turn the ignition to the "ON" position (do not start the engine) and check the pressure reading.
  • If the pressure is low, check the fuel pump and filter for issues and replace if necessary.
4. Inspect and Replace Spark Plugs
  • Remove the ignition coils using a socket set.
  • Remove the spark plugs using a spark plug socket.
  • Inspect the spark plugs for wear or fouling; replace with new plugs if needed (use OEM specifications).
  • Reinstall the ignition coils securely.
5. Clean or Replace Fuel Injectors
  • If the fuel injectors are suspected to be clogged, use a fuel injector cleaner or remove them for ultrasonic cleaning.
  • If cleaning does not restore function, replace the fuel injectors with new ones.
6. Reassemble and Reconnect
  • Reinstall any components removed during the inspection and repair process.
  • Reconnect the battery and ensure all connections are secure.
