Solution

1. Preparation

Gather tools: socket set, multimeter, wrench set, and safety gloves.
Ensure the vehicle is parked on a level surface with the engine off and the keys removed from the ignition.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative battery terminal using a wrench.
2. Clean any corrosion from the battery terminals and ensure they are tight.
3. Reconnect the negative terminal securely.

3. Starter Motor Access

Sub-steps:
1. Remove the engine cover if applicable.
2. Locate the starter motor (typically located near the transmission).
3. Disconnect the wiring harness from the starter motor.
4. Remove the bolts securing the starter motor using a socket set and remove it from the vehicle.

4. Starter Motor Testing

Sub-steps:
1. Use the multimeter to check for voltage at the starter motor terminal while a helper turns the key to the start position.
2. If no voltage is present, the issue may lie with the ignition switch or wiring.
3. If voltage is present but the starter does not engage, replace the starter motor.

5. Reinstallation

Sub-steps:
1. Install the new or tested starter motor in reverse order of removal.
2. Reconnect the wiring harness securely.
3. Reattach the bolts to the starter motor and torque them to the manufacturer's specifications.
4. Reconnect the battery terminal.
