Solution

1. Preparation

Gather required tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.
Ensure the vehicle is in a safe, well-ventilated area.

2. Battery Inspection and Replacement

Remove the battery terminals (negative first, then positive) using a socket wrench.
Clean any corrosion from the battery terminals and connectors with a wire brush.
Test the battery with a load tester; if it fails, replace it with a new one.
Reinstall the battery, connecting the positive terminal first, followed by the negative terminal.

3. Starter Motor Testing and Replacement

Locate the starter motor, typically near the transmission.
Disconnect the electrical connections from the starter motor.
Remove the starter motor mounting bolts with a socket set.
Carefully remove the starter motor from its mounting position.
Install a new starter motor by reversing the removal process and ensuring all connections are secure.

4. Fuel System Check

Inspect the fuel pump relay and fuse; replace if faulty.
If necessary, replace the fuel filter to ensure proper fuel flow.
If the fuel pump is faulty, remove and replace it following the vehicle's service manual.
