Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and a fuel pressure gauge.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Battery Inspection and Replacement

Check Battery Voltage
- Use a multimeter to measure the battery voltage; it should be at least 12.6 volts for optimal performance.
Clean Terminals
- Disconnect the battery terminals (negative first, then positive).
- Clean any corrosion from the terminals and cable ends using a wire brush and a mixture of baking soda and water.
Replace Battery (if necessary)
- If the battery voltage is low or the battery is old (over 4-5 years), replace it with a new one.
- Install the new battery, connecting the positive terminal first, followed by the negative.

3. Starter Motor Inspection

Check Starter Functionality
- Locate the starter motor and check the connections; ensure they are tight and free of corrosion.
- Test the starter by bypassing it with a jumper wire to see if it engages.
Replace Starter (if necessary)
- If the starter fails to engage, remove the starter motor by detaching the bolts and electrical connections.
- Install the new starter motor and reconnect all electrical connections securely.

4. Fuel System Check

Test Fuel Pump
- Turn the ignition to the "ON" position (do not start) and listen for the fuel pump's priming sound.
Check Fuel Filter
- Inspect the fuel filter for clogs; replace if necessary.
Inspect Fuel Lines
- Check for leaks or damage in the fuel lines; repair or replace as needed.
