Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to avoid electrical shock.

2. Battery Inspection and Replacement

Inspect the Battery:
- Remove the positive (+) and negative (-) terminals from the battery.
- Clean any corrosion using a mixture of baking soda and water, then dry.
- Reconnect terminals securely.
Replace the Battery (if necessary):
- If the battery voltage is below 12.6 volts or fails the load test, replace it.
- Remove the old battery by loosening the hold-down clamp and lifting it out.
- Install the new battery, ensuring correct orientation and connection (positive first).

3. Starter Inspection and Replacement

Inspect the Starter:
- Locate the starter motor; it's typically found near the engine/transmission junction.
- Inspect the wiring harness and connections to the starter for signs of wear or damage.
Replace the Starter (if necessary):
- Disconnect the battery again.
- Remove the electrical connectors from the starter (note their positions).
- Unbolt the starter from the engine block using a socket set.
- Install the new starter by securing it with bolts to the engine block.
- Reconnect electrical connectors to the new starter.

4. Final Checks

Reconnect the negative battery terminal.
Ensure all tools and materials are removed from the engine bay.
Test the vehicle by attempting to start the engine.
