Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe location, preferably on a flat surface.
Disconnect the negative terminal of the battery to ensure safety.

2. Battery Inspection

Inspect battery connections:
- Clean terminals with a wire brush if corroded.
- Tighten any loose connections.
If the battery is low (<12.4 volts), jump-start or charge the battery.

3. Starter Motor Testing

Locate the starter motor (usually near the transmission bell housing).
Use a multimeter to check for power at the starter terminal while someone turns the key:
- If power is present and clicking still occurs, proceed to replace the starter.
- If no power, trace back to the ignition switch and wiring.

4. Replace Starter Motor (if necessary)

Remove the negative battery terminal again for safety.
Disconnect the starter motor wiring:
- Remove the positive cable and the solenoid wire.
Unbolt the starter motor from the mounting brackets.
Install the new starter motor:
- Position it correctly and tighten the bolts to manufacturer specifications (typically 15-30 ft-lbs).
- Reconnect the wiring.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Attempt to start the vehicle and observe if it cranks normally.
