Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe location and the parking brake is engaged.
Disconnect the battery to prevent any electrical shorts.

2. Battery Inspection

Sub-steps:
1. Remove the negative terminal first, then the positive terminal from the battery.
2. Clean the battery terminals using a wire brush to remove any corrosion.
3. Reconnect the terminals securely, starting with the positive terminal followed by the negative terminal.

3. Starter Motor Testing

Sub-steps:
1. Locate the starter motor (usually near the transmission).
2. Disconnect the electrical connector from the starter.
3. Using jumper cables, connect the battery directly to the starter motor's terminal.
4. If the starter engages and turns over the engine, it indicates the starter is functional.

4. Fuse and Ignition Switch Check

Sub-steps:
1. Locate the fuse box and check the starting system fuses using a fuse puller.
2. Replace any blown fuses with the same amperage rating.
3. Test the ignition switch by checking for continuity when the key is turned to the start position.

5. Reassembly and Final Checks

Sub-steps:
1. Reconnect all components and ensure all connections are tight.
2. Reconnect the battery terminals securely.
3. Ensure all tools are cleared from the engine bay.
