Solution

1. Preparation

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

2. Inspect and Repair Fuel Lines

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Visually inspect all fuel lines for signs of wear, cracks, or leaks.
3. If a leak is found, replace the damaged section of the fuel line with new, manufacturer-approved fuel line.
4. Ensure all connections are tight and secure.

3. Replace Fuel Injector Seals

Sub-steps:
1. Locate the fuel injectors and remove any necessary components to access them.
2. Disconnect the fuel injector connectors.
3. Remove the fuel injector retaining clips and gently pull out the injectors.
4. Inspect the O-rings on the injectors and replace if damaged.
5. Reinstall the injectors with new O-rings, ensuring they are properly seated, and reattach the clips.

4. Test Fuel Pressure

Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail service port.
2. Turn the ignition to the ON position (do not start the engine) to prime the fuel system and record the pressure reading.
3. Compare the reading to the manufacturer specifications; if out of range, further investigation may be required.
