Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, basic hand tools
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Test the Fuel System

Sub-steps:
1. Reconnect the battery and turn the ignition to the 'ON' position without starting the engine.
2. Listen for the fuel pump's hum; if absent, check the fuel pump fuse.
3. If the pump operates, check fuel pressure using a fuel pressure gauge; it should meet manufacturer specifications.
4. If pressure is low, consider replacing the fuel filter and inspect for fuel line blockages.

3. Electrical System Check

Sub-steps:
1. Use a multimeter to check battery voltage; it should be around 12.6 volts.
2. If voltage is low, charge or replace the battery.
3. Inspect starter connections and ensure they are clean and secure; tighten as necessary.
4. If starter is faulty, replace the starter motor.

4. Addressing Fuel Cap Issues

Sub-steps:
1. Ensure the fuel cap is tight and undamaged; replace if necessary.
2. Clear any debris from the fuel filler neck.
3. If the fuel cap was loose, reset the check engine light using the OBD-II scanner.
