1. Preparation

Tools Required: Multimeter, OBD-II scanner, socket set, ammeter.
Safety Warnings: Disconnect the negative battery terminal before working on electrical systems.

2. Battery Replacement (if necessary)

Remove the negative battery terminal.
Remove the positive battery terminal.
Unscrew and remove the battery hold-down clamp.
Carefully lift the old battery out of the tray.
Place the new battery into the tray, ensuring it is secure.
Reinstall the hold-down clamp.
Connect the positive terminal first, followed by the negative terminal.

3. Starter Motor Replacement (if necessary)

Disconnect the battery as outlined in Preparation.
Locate the starter motor (typically near the engine and transmission junction).
Remove any covers or shields obstructing access.
Disconnect the electrical connectors from the starter motor.
Remove the mounting bolts using a socket set.
Carefully pull the starter motor out of its housing.
Install the new starter motor by reversing the removal steps, ensuring all connections are secure.

4. Fuel System Inspection (if necessary)

Ensure the vehicle is off and disconnect the battery.
Locate the fuel pump relay and remove it.
Turn the ignition to the 'On' position (do not start the engine) to test if the fuel pump activates.
If the pump does not activate, check the relay and wiring for faults.
