Solution

1. Battery Inspection and Replacement

Sub-steps:
1. Disconnect the negative battery terminal using a socket set.
2. Remove the positive battery terminal.
3. Visually inspect the battery for swelling or leaks.
4. If the battery voltage is low, replace it with a new, fully charged battery (Group size 94R recommended).
Tools Required: Socket set, multimeter.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Starter Motor Testing and Replacement

Sub-steps:
1. Locate the starter motor (typically near the transmission).
2. Disconnect the electrical connections from the starter motor.
3. Use a multimeter to check for voltage at the starter solenoid while turning the key to the start position.
4. If no voltage is present, further diagnose the ignition switch and wiring.
5. If voltage is present and the starter doesn't engage, remove the starter motor (typically requires a socket set).
6. Replace the starter motor with a new unit and reassemble all connections.
Tools Required: Socket set, multimeter.
Safety Warnings: Ensure the vehicle is in park or neutral with the parking brake engaged before working under the vehicle.

3. Ignition System Check

Sub-steps:
1. Inspect fuses related to the ignition and starter circuits; replace any blown fuses.
2. Check the ignition switch for proper operation; replace if faulty.
3. Confirm that the key fob battery is functioning, as a weak key fob battery can prevent ignition signal.
Tools Required: Fuse puller, multimeter.
Safety Warnings: Ensure the ignition is off before inspecting electrical components.
