Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe, well-ventilated area.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Battery Inspection

Sub-steps:
1. Clean battery terminals with a wire brush if corrosion is present.
2. Tighten any loose connections.
3. If the battery voltage is low, jump-start the vehicle using jumper cables or replace the battery with a new one (make sure it meets OEM specifications).

3. Starter Motor Testing

Sub-steps:
1. Locate the starter motor (usually near the transmission).
2. Use a multimeter to check power at the starter solenoid.
3. If there is power, the starter motor may need replacement; if no power, trace back to the ignition switch.

4. Fuse and Wiring Check

Sub-steps:
1. Locate the fuse box and identify the fuses related to the starting system.
2. Replace any blown fuses with the same amperage rating.
3. Inspect wiring for any visible damage or disconnections.

5. Reassembly

Sub-steps:
1. Reconnect the battery terminals, starting with the positive terminal.
2. Ensure all tools are removed from the engine bay.
3. Start the vehicle to verify if the issue is resolved.
