Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Fuel Lines

Tools Required: Socket set, line wrenches, fuel line disconnect tool.
Sub-steps:
1. Locate the fuel lines running from the fuel tank to the engine.
2. Use the line wrenches to carefully disconnect the fuel lines.
3. Inspect the lines for cracks or wear and replace if necessary.
4. Reconnect the new fuel lines securely, ensuring no leaks.

3. Check and Replace Fuel Injectors

Tools Required: Socket set, torque wrench, injector removal tool.
Sub-steps:
1. Remove the engine cover (if applicable) to access the fuel rail.
2. Disconnect the electrical connectors from the fuel injectors.
3. Remove the bolts securing the fuel rail and carefully lift it off.
4. Inspect the injectors for leaks and replace any that show signs of failure.
5. Reinstall the fuel rail and reconnect electrical connectors.

4. Inspect and Replace Fuel Cap

Tools Required: None (just hands).
Sub-steps:
1. Inspect the fuel cap for cracks or damage.
2. If necessary, replace the fuel cap with a new OEM part to ensure proper sealing.
3. Ensure the cap clicks into place securely.

5. Pressure Test the Fuel System

Tools Required: Fuel pressure gauge.
Sub-steps:
1. Attach the fuel pressure gauge to the fuel rail test port.
2. Turn the ignition to the "On" position without starting the engine to check pressure.
3. Observe the gauge to ensure it holds pressure; if not, further inspection of the fuel pump may be needed.
