Solution

1. Preparation

Gather tools: battery tester, multimeter, socket set, and screwdrivers.
Ensure the vehicle is in Park (automatic) or Neutral (manual) and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Check Battery Voltage:
- Remove the battery from the vehicle using a socket set.
- Use a multimeter to measure the voltage; if below 12.4 volts, recharge or replace the battery.
Clean Battery Terminals:
- Use a wire brush to clean any corrosion from the terminals and clamps.
- Reconnect the battery terminals securely.

3. Ignition Switch Testing and Replacement

Testing:
- Locate the ignition switch, usually found on the steering column.
- Disconnect the ignition switch connector.
- Use a multimeter to test for continuity between the terminals when the key is turned to the "Start" position.
Replacement:
- Remove the ignition switch from the steering column by unscrewing the mounting screws.
- Install the new ignition switch and reattach the connector.

4. Starter Relay and Motor Inspection

Relay Check:
- Locate the starter relay in the fuse box.
- Swap it with a similar relay (e.g., horn relay) to see if the issue resolves.
Starter Motor Inspection:
- Locate the starter motor under the vehicle.
- Inspect for loose connections and any signs of wear or damage.
- If necessary, remove the starter motor using a socket set and replace it.
