Solution

1. Preparation

Disconnect the battery to ensure safety while working on electrical components.
Gather tools: socket set, multimeter, battery terminal cleaner, jump starter.

2. Battery Inspection and Replacement

Check battery condition:
- If the battery voltage is below 12.4 volts, charge it using a battery charger.
- If the battery is over 3 years old or showing signs of swelling or leakage, consider replacing it.
Remove battery (if replacing):
1. Use a socket set to loosen and remove the negative terminal first, followed by the positive terminal.
2. Remove any battery hold-down clamps and lift the battery out carefully.

3. Starter and Wiring Inspection

Inspect starter motor:
1. Locate the starter motor, which is usually mounted on the lower side of the engine.
2. Check connections for corrosion or looseness; clean and tighten as necessary.
3. If the starter motor is faulty, remove it by:
  - Disconnecting the wiring harness and solenoid wire.
  - Removing the bolts securing the starter to the engine block using a socket set.
  - Replace with a new starter if necessary.

4. Reconnect and Test

Reconnect the battery:
1. Install the new or recharged battery by securing the positive terminal first, followed by the negative terminal.
2. Ensure all connections are tight and clean.
Test starting the vehicle:
1. Insert the key and attempt to start the vehicle.
2. Observe for any clicking sounds or signs of life from the engine.
