Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe and stable position, with the ignition off.
Disconnect the negative battery terminal to avoid electrical shock.

2. Battery Inspection and Replacement

Inspect Battery:
- Clean any corrosion from battery terminals using a mixture of baking soda and water.
- Tighten any loose connections.
Test Battery:
- If battery voltage is below 12.6 volts, proceed to replace the battery.
Replace Battery:
- Remove the negative terminal followed by the positive terminal.
- Remove any hold-down brackets and lift the battery out.
- Place the new battery in the tray.
- Reattach the positive terminal first, then the negative terminal.
- Ensure connections are tight.

3. Starter Motor Inspection

Remove Starter:
- Disconnect the negative battery terminal (if not done previously).
- Locate the starter motor (usually near the transmission).
- Remove any electrical connections from the starter.
- Unbolt the starter motor from its mounting (typically 2-3 bolts).
Inspect Starter:
- Check for any visible damage or wear.
- Test the starter motor directly using jumper cables to see if it engages.
Replace Starter (if necessary):
- Install the new starter motor by bolting it into place.
- Reconnect the electrical connections.

4. Relay and Fuse Check

Check Starter Relay:
- Locate the fuse box and find the starter relay.
- Swap the starter relay with an identical relay (e.g., horn relay) to test functionality.
Check Fuses:
- Inspect the fuse associated with the starting system and replace if blown.
