Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe, well-ventilated area.
Disconnect the negative terminal of the battery before starting any electrical work.

2. Battery Inspection and Replacement

Sub-steps:
1. If the battery voltage is low, charge the battery using a battery charger or replace it if it cannot hold a charge.
2. Clean the battery terminals using a wire brush and a solution of baking soda and water to remove corrosion.
3. Reconnect the battery terminals securely and ensure no corrosion is present.

3. Fuse and Relay Check

Sub-steps:
1. Remove the fuse box cover and locate the ignition and starter motor fuses.
2. Replace any blown fuses with fuses of the same amperage.
3. Locate the starter relay, remove it, and test it by swapping with a similar relay. If no click is heard when starting, replace the relay.

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 in the "start" position.
3. If there is no continuity, replace the ignition switch.

5. Starter Motor Inspection

Sub-steps:
1. If issues persist, disconnect the wiring harness from the starter motor.
2. Use a multimeter to test for voltage at the starter motor connector while turning the ignition to the start position.
3. If voltage is present but the starter does not engage, replace the starter motor.
