Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative terminal of the battery to prevent electrical shocks.

2. Battery Inspection

Tools Required: Multimeter, wire brush, wrench.
Sub-steps:
1. Use the multimeter to check the battery voltage.
2. If voltage is low, charge or replace the battery.
3. Clean battery terminals with a wire brush and ensure tight connections.

3. Starter Relay and Wiring Check

Tools Required: Screwdriver, multimeter.
Sub-steps:
1. Locate the starter relay in the fuse box.
2. Swap the starter relay with a similar one to test functionality.
3. If the clicking persists, inspect wiring to the starter motor for any signs of wear or disconnection.

4. Ignition Switch Testing

Tools Required: Multimeter.
Sub-steps:
1. Remove the ignition switch from the steering column.
2. Use the multimeter to check for continuity at the switch terminals.
3. Replace the ignition switch if it fails the continuity test.

5. Starter Motor Inspection

Tools Required: Socket set, wrench.
Sub-steps:
1. Locate the starter motor, usually near the transmission.
2. Check wiring to the starter motor for any loose connections.
3. If connections are secure, test the starter motor by applying direct voltage (if safe to do so).
4. Replace the starter motor if it does not engage.
