how to clean fuel injectors in Honda Accord 9th Generation (2013-2017)

Solution

1. Preparation

• Gather tools and materials needed for the job.
• Tools Required:
  • Socket set
  • Torque wrench
  • Fuel pressure gauge
  • Injector cleaning kit (with appropriate cleaning solvent)
  • Safety goggles and gloves
• Safety Warnings:
  • Disconnect the battery before working on fuel systems to avoid sparks.
  • Work in a well-ventilated area.

2. Remove Fuel Rail

1. Relieve fuel pressure by removing the fuel pump relay and starting the engine until it stalls.
2. Disconnect the negative battery terminal.
3. Remove the engine cover (if applicable) for better access.
4. Disconnect the fuel lines from the fuel rail using the appropriate tools.
5. Unplug the electrical connectors from each fuel injector.
6. Unbolt the fuel rail from the intake manifold using a socket wrench.
7. Carefully lift the fuel rail away from the engine, ensuring the injectors come out with it.

3. Clean Fuel Injectors

1. Place the fuel injectors in the cleaning kit according to the manufacturer's instructions.
2. Fill the cleaning kit with the appropriate cleaning solvent.
3. Allow the cleaning solvent to flow through the injectors as per the kit instructions (typically involves pressurizing the system).
4. After cleaning, check each injector for proper spray pattern and functionality.
5. Wipe any excess solvent from the injectors and inspect O-rings for damage.

4. Reinstall Fuel Rail and Components

1. Apply a small amount of engine oil to the O-rings of each injector to ensure a proper seal.
2. Insert the cleaned injectors back into the fuel rail.
3. Reinstall the fuel rail onto the intake manifold and tighten bolts to the manufacturer's specified torque.
4. Reconnect the fuel lines and electrical connectors to the injectors.
5. Reattach the engine cover and reconnect the battery terminal.
6. Reinstall the fuel pump relay.
