Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, battery terminal cleaner, and a load tester.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Battery Maintenance

Disconnect Battery: Remove the negative (-) terminal first, then the positive (+) terminal.
Clean Terminals: Use a battery terminal cleaner to remove corrosion from battery posts and cable ends.
Reconnect Battery: Attach the positive (+) terminal first, then the negative (-) terminal. Ensure connections are tight.

3. Starter Motor Inspection

Remove Starter: Disconnect electrical connections and mounting bolts to remove the starter from the engine.
Inspect the Starter: Check for signs of wear or damage, and ensure the pinion gear moves freely.
Test Starter: Use a jumper wire to connect the starter directly to the battery to see if it engages.

4. Relay and Fuse Replacement

Replace Starter Relay: If the relay is faulty, replace it with a new one from an auto parts store.
Check and Replace Fuses: Replace any blown fuses related to the starting system.
