Solution

1. Preparation

Gather tools and parts: multimeter, socket set, screwdriver, replacement fuses, and starter relay if necessary.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection

Check Battery Health
- Use a multimeter to measure the battery voltage. If below 12.4 volts, charge or replace the battery.
Clean Battery Terminals
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion on terminals and battery posts with a wire brush and battery cleaner.
- Reconnect terminals securely.

3. Fuse and Relay Check

Inspect Ignition Fuse
- Locate the fuse box under the dashboard or hood.
- Remove the ignition fuse and inspect for any signs of damage. Replace if blown.
Test Starter Relay
- Locate the starter relay in the fuse box.
- Swap it with a similar relay to check for operation or test it using a multimeter for continuity.

4. Ignition Switch Testing

Check Ignition Switch
- Remove the steering column cover to access the ignition switch.
- Disconnect the harness and use a multimeter to test for continuity in the switch when turned to "start."
- Replace the ignition switch if it fails the continuity test.
