Solution

1. Preparation

Tools Required: Safety goggles, gloves, shop towels, OBD-II scanner, fuel pressure gauge.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Inspect Fuel Lines

Sub-steps:
- Visually inspect all fuel lines and connections for cracks or signs of wear.
- Use a flashlight to check hard-to-see areas.
- Tighten any loose connections using the appropriate socket or wrench.
- Replace any damaged fuel lines with OEM or quality aftermarket parts.

3. Replace Fuel Filter (if necessary)

Sub-steps:
- Locate the fuel filter (refer to the owner's manual for specific location).
- Using the appropriate socket, remove the mounting bolts.
- Disconnect the inlet and outlet fuel lines (use shop towels to catch any spilled fuel).
- Install the new fuel filter, ensuring the flow direction is correct.
- Reconnect the fuel lines and secure the filter in place.

4. Test Fuel Injectors

Sub-steps:
- Disconnect the electrical connector from each fuel injector.
- Use a multimeter to check the resistance of each injector (compare readings to specifications).
- If any injector is faulty, replace it with a new unit.
- Reconnect all electrical connections once repairs are completed.

5. Reassemble and Check for Leaks

Sub-steps:
- Reconnect the battery.
- Start the engine and let it idle.
- Check for any fuel leaks around the repaired areas.
- If no leaks are found, take the vehicle for a short test drive to ensure everything is functioning properly.
