Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a flat surface and use wheel chocks for safety.

2. Inspect and Replace Fuel Lines

Sub-steps:
1. Visually inspect the fuel lines for cracks, wear, or leaks.
2. If damaged, relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
3. Use a socket set to disconnect the fuel lines from the fuel rail and tank.
4. Replace the damaged fuel lines with new OEM parts, ensuring proper routing and securing with clamps.
Tools Required: Socket set, fuel line disconnect tool.
Safety Warnings: Always wear gloves and work in a well-ventilated area due to fuel vapors.

3. Test and Replace Fuel Injectors

Sub-steps:
1. Remove the engine cover if applicable.
2. Disconnect the electrical connectors from the fuel injectors.
3. Use a wrench to remove the fuel rail and the injectors.
4. Inspect the injector O-rings for wear or damage and replace as necessary.
5. Reinstall the injectors and fuel rail, ensuring a snug fit and proper orientation.
Tools Required: Wrench set, injector O-ring kit.
Safety Warnings: Be careful with fuel spills; use rags to absorb any excess.

4. Verify Fuel Pressure

Sub-steps:
1. Reconnect the fuel pump fuse and battery terminal.
2. Attach the fuel pressure gauge to the fuel rail.
3. Turn the ignition to the "ON" position (without starting) and check the pressure readings; they should be within the manufacturer's specifications.
4. If pressure is low, inspect the fuel pump and replace if necessary.
Tools Required: Fuel pressure gauge.
Safety Warnings: Ensure all connections are secure to prevent fuel leaks during testing.
