Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a flat surface with the ignition off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Sub-steps:
1. Inspect battery terminals for corrosion; clean using a wire brush and baking soda solution if necessary.
2. If the battery voltage is below 12.4 volts, charge the battery or replace it if it's old or weak.
3. Reconnect the battery terminals and ensure they are tight.

3. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor under the vehicle (usually near the transmission).
2. Use a multimeter to check for voltage at the starter solenoid when the ignition is turned on.
3. If no voltage is present, trace back to the ignition switch and check for continuity.
4. If voltage is present but the starter does not engage, remove the starter motor for further testing or replacement.

4. Replacing the Starter Motor (if necessary)

Sub-steps:
1. Disconnect any electrical connectors attached to the starter.
2. Remove the mounting bolts using a socket set (typically 12mm or 14mm).
3. Carefully extract the starter from its location.
4. Install the new starter by reversing the removal steps, ensuring all connections are tight.
