Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is in a safe and accessible work area.

2. Inspect and Clean Battery Connections

Remove the positive and negative battery terminals using a socket wrench.
Clean the terminals and battery posts using a wire brush until shiny.
Reconnect the battery terminals securely and ensure there are no loose connections.

3. Test and Replace Starter Relay

Locate the starter relay in the under-hood fuse box.
Remove the relay using pliers or your fingers.
Replace with a new starter relay if necessary (part number may vary; consult service manual for specifics).

4. Remove and Test Starter Motor

Remove any components obstructing access to the starter motor (e.g., air intake duct).
Disconnect the electrical connectors from the starter motor.
Unbolt the starter motor from its mounting using a socket set (typically two or three bolts).
Bench test the starter motor by connecting it directly to a charged battery; check for cranking action.
If the starter does not engage, replace it with a new or reconditioned starter motor.

5. Reassemble and Reconnect

Install the new or tested starter motor back into its mounting position.
Reconnect electrical connectors securely to the starter.
Reattach any components removed for access.
Reconnect the negative battery terminal.
