Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is in a safe, well-ventilated area.
Disconnect the battery to avoid any electrical hazards.

2. Check Battery Connections

Inspect the positive and negative battery terminals for tightness.
Clean any corrosion with a wire brush and terminal cleaner.
Reconnect the battery terminals securely.

3. Inspect and Test the Starter Motor

Locate the starter motor (typically near the engine block).
Use a multimeter to check for voltage at the starter terminal while someone attempts to start the vehicle.
If no voltage is present, the starter may need replacement; if there is voltage but it doesn’t engage, replace the starter motor.

4. Inspect Fuses

Locate the fuse box in the engine compartment and the interior.
Remove and inspect the fuses related to the ignition and starter systems.
Replace any blown fuses with the same amperage rating.

5. Check Fuel Pump

Turn the ignition key to the "ON" position (without starting).
Listen for the fuel pump's humming sound from the rear of the vehicle.
If the pump is silent, check the fuel pump relay and replace it if faulty.

6. Inspect the Ignition Switch

Remove the steering column cover to access the ignition switch.
Use a multimeter to check for proper voltage output from the ignition switch when turned.
Replace the ignition switch if it is not functioning correctly.
