Solution

1. Preparation

Gather tools: multimeter, socket set, screwdriver, and safety gloves.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Battery Inspection

Sub-steps:
1. Remove the battery terminals, starting with the negative terminal.
2. Clean any corrosion from the terminals and battery posts using a wire brush.
3. Reconnect the battery terminals securely, ensuring a tight fit.

3. Starter Relay and Fuse Check

Sub-steps:
1. Locate the fuse box under the dashboard or hood.
2. Identify the starter relay and remove it from the socket.
3. Swap it with a similar relay to test functionality.
4. Check the fuses related to the starting system using a fuse tester; replace any blown fuses.

4. Ignition Switch Testing

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Using a multimeter, check for continuity in the ignition switch when turned to the "start" position.
3. If no continuity is detected, replace the ignition switch.

5. Starter and Wiring Inspection

Sub-steps:
1. Locate the starter motor, typically found on the lower side of the engine near the transmission.
2. Check the connections to the starter for tightness and any signs of corrosion.
3. If accessible, test the starter motor directly by applying 12 volts; replace if it remains inoperative.
