Solution

1. Preparation

Ensure the vehicle is in park or neutral and the parking brake is engaged.
Disconnect the battery by removing the negative terminal first, followed by the positive terminal.

2. Battery Inspection

Tools Required: Multimeter, socket set, wire brush
Clean battery terminals using a wire brush to remove any corrosion.
Reconnect the battery terminals, ensuring they are tight and secure.
Check the battery voltage again to confirm it's adequate.

3. Starter Relay and Fuse Check

Tools Required: Multimeter, fuse puller
Locate the fuse box and check the starter fuse for continuity using a multimeter; replace if blown.
Test the starter relay by swapping it with another relay of the same type (e.g., horn relay) to see if the issue persists.

4. Starter Inspection

Tools Required: Socket set, ratchet
If the battery and relay are functioning, remove the starter from the engine.
Inspect the starter for signs of wear or damage. Clean any debris around the starter mounting area.
Test the starter with a bench test to see if it engages properly.

5. Reassembly

Reinstall any components removed during the inspection, ensuring all connections are secure and correctly positioned.
Reconnect the battery terminals, positive first and then negative.
