Solution

1. Preparation

Gather tools and parts required for the repair.
Tools Required: OBD-II scanner, multimeter, socket set, screwdriver set.
Parts Required: Fuel pump relay (if faulty), battery (if weak or dead).
Disconnect the battery to ensure safety during repairs.

2. Test the Battery

Remove the battery terminals (negative first, then positive).
Use a multimeter to test voltage; if below 12.4V, replace the battery.
Clean battery terminals and reconnect them securely.

3. Inspect and Replace Fuel Pump Relay

Locate the fuel pump relay in the fuse box.
Remove the relay and check for continuity using a multimeter.
If faulty, replace it with a new relay.
Reinstall the relay and ensure it clicks into place.

4. Examine the Fuel System

Check the fuel lines for leaks or blockages.
If no leaks are found, listen for a humming noise from the fuel tank; this indicates that the fuel pump is operational.
If the pump is silent, consider replacing it.

5. Reconnect Battery and Test Start

Reconnect the battery terminals (positive first, then negative).
Attempt to start the vehicle.
If the vehicle starts, monitor for any unusual noises or warning lights.
