Solution

1. Preparation

Gather tools: multimeter, socket set, jumper cables, and safety glasses.
Ensure the vehicle is in 'Park' or 'Neutral' and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion on the terminals with a wire brush.
- Reconnect the terminals securely and ensure they are tight.
Replace Battery (if necessary):
- If the battery voltage is below 12.4 volts, consider replacing it.
- Remove the battery hold-down bracket and carefully lift the battery out.
- Replace with a new battery of the same specifications (check CCA ratings).

3. Starter Motor Testing and Replacement

Testing the Starter:
- Reconnect the battery and check for voltage at the starter terminal while someone turns the key.
- If no voltage is present, the issue may be with the ignition switch or start relay.
Replace Starter (if necessary):
- Disconnect the negative battery terminal.
- Remove any components obstructing access to the starter.
- Unbolt and disconnect the starter motor wiring (note the connections for reinstallation).
- Install the new starter motor securely and reconnect the wiring.

4. Final Assembly

Reinstall any components removed for access.
Reconnect the negative battery terminal.
Test the vehicle to ensure it starts properly.
