Disconnect the negative battery terminal using a socket set.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Remove corrosion using a wire brush.
- Tighten any loose connections.
Battery Testing:
- If voltage is below 12.4 volts, charge the battery fully or replace it if it fails a load test.

3. Starter Motor Inspection

Remove Starter Motor:
- Disconnect the wiring harness from the starter.
- Unbolt the starter from its mounting using a socket set.
Test Starter:
- Connect the starter to a separate battery to test its operation.
- Replace the starter if it does not engage.

4. Fuel System Check

Check Fuel Pump:
- Remove the fuel pump fuse from the fuse box.
- Test the fuel pump relay by swapping it with a similar relay.
- Replace the relay if the fuel pump does not activate.

5. Reassemble and Reconnect

Reinstall the starter motor and reconnect all wiring.
Reconnect the battery terminal and ensure all connections are tight.
