Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, wrenches, and a battery terminal cleaner.
Ensure the vehicle is in a safe location with the ignition off.
Disconnect the battery before starting any electrical work.

2. Battery Check and Replacement

Inspect Battery: Remove the battery terminals using a socket wrench. Clean any corrosion with a battery terminal cleaner.
Test Battery Voltage: Reconnect the battery terminals and use a multimeter to check voltage. If below 12.4 volts, consider charging or replacing.
Replace Battery (if necessary): If the battery is faulty, remove it and replace it with a new one, ensuring it meets the manufacturer's specifications. Torque the battery terminals to manufacturer specifications.

3. Starter Motor Inspection and Replacement

Access Starter Motor: Remove any components obstructing access to the starter motor.
Test Starter Motor: Verify voltage at the starter terminal during a start attempt. If no voltage is present, check wiring and connections.
Replace Starter (if necessary): If the starter is faulty, remove it by unscrewing the mounting bolts. Install the new starter, ensuring all electrical connections are secure and torque bolts to manufacturer specifications.

4. Fuel System Check

Inspect Fuel Pump Operation: Turn the ignition to the "ON" position and listen for the fuel pump priming sound.
Replace Fuel Pump (if necessary): If the pump is not operational, remove the fuel tank access panel (if applicable) or lower the fuel tank. Disconnect the fuel lines and electrical connectors, then replace with a new fuel pump, ensuring to reconnect all components securely.
