Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is in a safe, flat area and the ignition is off.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Clean any corrosion with a wire brush and a mixture of baking soda and water.
- Ensure terminals are tightly secured.
Test Battery Voltage:
- Connect the multimeter leads to the battery terminals.
- If voltage is below 12.6 volts, proceed to replace the battery.
Replace Battery (if necessary):
- Remove the battery hold-down bracket using a socket set.
- Disconnect the positive terminal first, followed by the negative terminal.
- Remove the old battery and install the new one in reverse order.
- Reconnect the negative terminal last and tighten securely.

3. Starter Motor Inspection and Replacement

Inspect Starter Motor Connections:
- Locate the starter motor under the vehicle.
- Check the wiring harness for any signs of damage or corrosion.
- Ensure all connections are tight.
Testing the Starter Motor:
- If the battery is good, use a multimeter to check for voltage at the starter motor when the key is turned.
- If no voltage is present, further diagnose the ignition switch and starter relay.
Replace Starter Motor (if necessary):
- Disconnect the battery again for safety.
- Remove the starter motor bolts using a socket set.
- Disconnect the electrical connectors from the starter.
- Install the new starter motor, reconnect the electrical connections, and secure with bolts.
- Reconnect the battery.
