Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, socket set, screwdriver set, replacement starter motor (if needed).
Ensure the vehicle is in a safe, well-ventilated area and that the ignition is off.

2. Inspect Fuses

Identify the fuse box location (typically under the dashboard or hood).
Remove the cover and check the fuses related to the ignition and starter.
Replace any blown fuses with new ones of the correct amperage.

3. Test the Ignition Switch

Disconnect the battery to prevent any electrical shorts.
Remove the steering column cover to access the ignition switch.
Use a multimeter to check for continuity at the ignition switch terminals when the key is turned to the start position.
If no continuity is detected, replace the ignition switch.

4. Examine Starter Motor

Ensure the battery is disconnected.
Locate the starter motor (usually near the transmission).
Inspect the wiring and connections for corrosion or damage.
If necessary, remove the starter motor by unbolting it and disconnecting the power and ground wires.
Bench test the starter motor to see if it engages when power is applied. Replace if faulty.

5. Check Fuel Pump Functionality

Turn the ignition key to the "ON" position without starting the engine.
Listen for the fuel pump's humming sound from the fuel tank.
If there is no sound, inspect the fuel pump relay and replace if needed. If the relay is functional, the fuel pump may need replacement.
