Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to ensure safety.
  • Ensure the vehicle is on a flat surface and properly supported.
2. Remove the Fuel Pump Relay
  • Locate the fuel pump relay in the fuse box (refer to the owner's manual for exact location).
  • Using a socket set, carefully remove the screws or clips holding the fuse box cover.
  • Gently pull the fuel pump relay out of its socket.
3. Inspect and Test the Relay
  • Check the relay for any signs of burnt contacts or corrosion.
  • Using a multimeter, set it to the resistance setting and test the relay terminals for continuity; if there is no continuity, replace the relay.
4. Replace the Fuel Pump Relay
  • If the relay is faulty, install a new relay by aligning it with the socket and pressing down until it clicks into place.
  • Reinstall the fuse box cover securely.
5. Reconnect Battery and Test
  • Reconnect the negative battery terminal.
  • Turn the ignition to the "ON" position (do not start) and listen for the fuel pump to activate.
  • Attempt to start the engine to verify proper operation.
