Solution

1. Preparation

Gather tools: Multimeter, OBD-II scanner, socket set, screwdriver set, and safety goggles.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Battery Inspection and Replacement

Inspect Battery Condition
- Clean terminals with a wire brush if corrosion is present.
- Reconnect the battery and measure voltage; if below 12.4 volts, proceed to replacement.
Replace Battery (if necessary)
- Remove the battery hold-down bracket using a socket set.
- Disconnect the positive terminal first, followed by the negative terminal.
- Remove the old battery and install the new one in reverse order.
- Reconnect the terminals (negative first, then positive) and tighten securely.

3. Starter Motor Check

Test Starter Motor
- Locate the starter motor and ensure connections are tight.
- Use a multimeter to check voltage at the starter when turning the key.
- If there is no voltage and the battery is good, replace the starter motor.
- Remove the starter motor using the socket set and install the new starter.

4. Fuel System Inspection

Check Fuel Pump
- Turn the ignition to the "on" position without starting the engine and listen for the fuel pump sound.
- If no sound is heard, test the fuel pump relay and fuse.
- If both are functional, replace the fuel pump.

5. Ignition System Check

Inspect Spark Plugs and Coils
- Remove spark plugs using a socket set and inspect for wear or carbon buildup.
- Replace any worn plugs and check ignition coils for cracks or damage; replace if necessary.
