Solution

1. Preparation

Gather necessary tools: multimeter, socket set, screwdriver, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery cable to avoid electrical shock.

2. Battery Inspection

Remove the battery terminals (negative first, then positive).
Clean the terminals and cable ends with a wire brush to remove corrosion.
Reconnect the battery terminals securely, ensuring a tight fit.

3. Starter Relay and Ignition Switch Check

Locate the starter relay in the fuse box under the hood.
Remove the starter relay and test it with a multimeter for continuity.
If the relay is faulty, replace it with a new one.
Check the ignition switch for functionality by testing for voltage at the starter solenoid when the ignition is turned on.

4. Starter Motor Inspection

If the battery and relay are functional, locate the starter motor.
Remove the starter motor electrical connectors and inspect for damage.
Remove the bolts securing the starter motor and pull it out for inspection.
Test the starter motor operation by applying direct battery voltage to it; if it does not engage, replace the starter.

5. Reassemble and Test

Reinstall the starter motor and secure it with bolts.
Reconnect the electrical connectors to the starter.
Reconnect the battery terminals (positive first, then negative).
Attempt to start the engine.
