Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal for safety.

2. Battery Inspection

Remove the battery terminals (negative first, then positive).
Clean any corrosion from the terminals and cable connectors using a wire brush.
Reconnect the battery terminals securely.

3. Starter Motor Testing

Locate the starter motor (usually near the transmission).
Disconnect the wiring harness from the starter.
Use a multimeter to check for voltage at the starter terminal while turning the key to the start position.
If there is no voltage, replace the starter relay or check the ignition switch.

4. Starter Replacement (if necessary)

If the starter is faulty, remove it by:
- Unbolting the starter from the engine block using a socket set.
- Carefully maneuvering the starter out of the engine compartment.
Install the new starter:
- Position the new starter and secure it with bolts to the engine block.
- Reconnect the wiring harness to the starter.
Reconnect the battery terminals (positive first, then negative).

5. Final Checks

Ensure all tools and debris are removed from the engine compartment.
Reconnect the negative battery terminal.
