Solution

1. Preparation

Gather tools: multimeter, OBD-II scanner, socket set, torque wrench, and cleaning supplies.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Battery Inspection

Disconnect the negative terminal of the battery to prevent electrical shorts.
Clean any corrosion from the battery terminals using a wire brush and baking soda solution.
Tighten the battery terminals securely.
Reconnect the negative terminal.

3. Battery Testing

Reconnect the multimeter to the battery and check the voltage.
If the voltage is below 12.4 volts, charge the battery using a suitable battery charger.
If the battery fails to hold a charge, replace with a new battery of the same specifications.

4. Starter Motor Check

Locate the starter motor and ensure all connections are secure.
Use the multimeter to test the voltage at the starter motor when attempting to start the engine.
If there is no voltage or if the starter is faulty, remove and replace the starter motor.

5. Fuel and Ignition System Check

Use a fuel pressure gauge to check the fuel system pressure.
If pressure is low, inspect the fuel pump and fuel filter for blockages or failure.
Inspect spark plugs for wear or fouling; replace if necessary.
