Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent accidental short circuits.

2. Battery Inspection

Sub-steps:
1. Clean any corrosion from the battery terminals using a wire brush.
2. Tighten the battery connections to ensure a solid contact.
3. If the battery voltage is low (below 12.4 volts), charge it fully or replace it if it is old.

3. Starter Relay Check

Sub-steps:
1. Locate the starter relay in the fuse box (consult the owner’s manual for exact location).
2. Remove the starter relay and visually inspect it for any signs of damage.
3. Swap it with a similar relay (like the horn relay) to check for functionality.

4. Starter Motor Inspection

Sub-steps:
1. If the problem persists, locate the starter motor.
2. Check the wiring connections to the starter for tightness and damage.
3. Use a multimeter to check for voltage at the starter motor while someone turns the key to start.

5. Ignition Switch Inspection

Sub-steps:
1. If the starter motor is not engaging, check the ignition switch for wear.
2. Remove the ignition switch (consult the service manual for instructions).
3. Test the switch with a multimeter to ensure it is functioning correctly.
