Solution

1. Preparation

Gather all necessary tools and parts before starting.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Sub-steps:
1. Reconnect the negative battery terminal and test the battery voltage again; if voltage is low, replace the battery.
2. Remove the battery by loosening the hold-down bracket and disconnecting the positive terminal first, then the negative terminal.
3. Install the new battery by connecting the positive terminal first, followed by the negative terminal, and secure the hold-down bracket.

3. Starter Motor Inspection and Replacement

Sub-steps:
1. Locate the starter motor (usually mounted near the transmission).
2. Disconnect the battery negative terminal again for safety.
3. Remove the electrical connections from the starter motor.
4. Unbolt the starter motor from its mounting position (typically 2-3 bolts).
5. Replace with a new or refurbished starter motor and reinstall it, tightening bolts to manufacturer specifications (usually around 15-20 ft-lbs).
6. Reconnect the electrical connections to the starter motor.

4. Ignition Switch Inspection (if needed)

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Test the ignition switch with a multimeter to ensure it is functioning correctly.
3. Replace the ignition switch if it shows no continuity when the key is turned to the start position.
