Repair Instructions

Step 1: Replace the Fuel Pump Relay

Locate the Relay: Open the hood and locate the engine compartment fuse box. Refer to the owner's manual for the exact location of the fuel pump relay.
Remove the Relay:
- Using your fingers or pliers, carefully pull the relay out of its socket.
Install the New Relay:
- Take the new relay and align it with the socket. Press firmly until it is seated properly.

Step 2: Check the Fuse

Inspect the Fuel Pump Fuse: Check the fuse related to the fuel pump in the fuse panel. Replace it if it is blown.

Step 3: Test the System

Reconnect Battery (if disconnected): If you had disconnected the battery, reconnect it.
Turn the Ignition On: Turn the key to the "ON" position and listen for the fuel pump operation.
Start the Engine: If the pump operates and you hear it, try starting the vehicle.

Step 4: Further Troubleshooting (if necessary)

If the car still does not start, revisit the wiring and ensure all connections are secure. Check for any damaged wires or connectors which may have caused the relay to fail initially.
Inspect the fuel pump itself if the relay and fuse are confirmed to be functional.

Always ensure safety measures are taken during the repair process, and if the issue persists after replacing the relay, further investigation into the fuel system may be required.
