Solution
1. Preparation
  • Gather tools: OBD-II scanner, multimeter, socket set, and wire connectors.
  • Disconnect the negative battery terminal to prevent electrical shock.
2. Remove the Fuel Pump Relay
  • Locate the fuel pump relay in the under-hood fuse box.
  • Use a socket or pliers to remove the relay from its socket.
  • Inspect the relay for any signs of damage or corrosion.
3. Test the Relay
  • Set the multimeter to the continuity setting.
  • Connect the multimeter probes to the relay terminals and test for continuity.
  • If the relay fails the continuity test, proceed to replace it.
4. Replace the Fuel Pump Relay
  • Purchase a new fuel pump relay compatible with the 2012-2015 Honda Civic.
  • Insert the new relay into the same socket where the old relay was located.
5. Check and Replace Fuses
  • Inspect the fuse box for the fuel pump fuse; replace it if it is blown.
  • Ensure all connections are tight and secure.
6. Reconnect Battery and Test
  • Reconnect the negative battery terminal.
  • Turn the ignition to the "ON" position and listen for the fuel pump activation.
  • Start the engine to confirm the repair.
