Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to avoid electrical shock.
2. Remove the Fuel Pump Relay
  • Locate the fuel pump relay in the fuse box (typically found under the dashboard or in the engine compartment).
  • Use a socket set to remove any screws or clips securing the fuse box cover.
  • Identify the fuel pump relay and gently pull it out of its socket.
3. Inspect and Test the Relay
  • Use a multimeter to check for continuity across the relay terminals.
    • Set the multimeter to the resistance setting.
    • If there is no continuity, replace the relay.
  • If the relay is functioning, inspect the relay socket for corrosion or damage.
4. Replace the Relay
  • Insert a new fuel pump relay into the socket, ensuring it is seated properly.
  • Reattach the fuse box cover and secure it with screws or clips.
5. Reconnect Battery and Test
  • Reconnect the negative battery terminal.
  • Start the vehicle to check if the issue is resolved.
