why does my Honda Accord Eleventh Generation (2023-present) keep stalling

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Spark Plugs

• Sub-steps:
  1. Remove the ignition coil cover if necessary.
  2. Disconnect the electrical connectors from the ignition coils.
  3. Remove the ignition coils using a socket set.
  4. Unscrew and remove the spark plugs using a spark plug socket.
  5. Inspect the spark plugs for wear; replace with new ones if needed (use OEM specifications).
  6. Reinstall new spark plugs and ignition coils, ensuring they are torqued to manufacturer specifications (usually around 13-15 lb-ft).

3. Check Fuel Pump

• Sub-steps:
  1. Access the fuel pump by removing the rear seat or trunk panel as necessary.
  2. Connect a fuel pressure gauge to the fuel line.
  3. Turn the ignition key to the “ON” position (do not start the engine) and check the pressure reading (should be around 40-50 psi, refer to service manual).
  4. If the pressure is low, replace the fuel pump.
  5. Reassemble any components removed to access the fuel pump.

4. Inspect Battery and Charging System

• Sub-steps:
  1. Use a multimeter to check the battery voltage (should read approximately 12.6 volts when off and 13.7-14.7 volts when running).
  2. Clean battery terminals and ensure tight connections.
  3. If the battery voltage is low, replace the battery with a new one.
  4. Test the alternator output while the engine is running to ensure it is functioning correctly.
