Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, fuel pressure gauge, fuel injector cleaning kit.
Disconnect the negative battery terminal to prevent electrical shorts.
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.

2. Remove Fuel Injectors

Sub-steps:
1. Remove the engine cover if applicable.
2. Disconnect the electrical connectors from the fuel injectors.
3. Remove any brackets or components blocking access to the fuel rail.
4. Unbolt the fuel rail from the intake manifold; be cautious of residual fuel.
5. Carefully pull the fuel injectors out of the fuel rail.

3. Inspect and Clean Fuel Injectors

Sub-steps:
1. Visually inspect the injectors for any signs of damage.
2. Use a fuel injector cleaning kit to clean each injector according to the manufacturer’s instructions.
3. Check the injector o-rings and replace if they are worn or damaged.

4. Install New or Reconditioned Injectors

Sub-steps:
1. Apply a small amount of clean engine oil to the new o-rings for easier installation.
2. Insert the fuel injectors back into the fuel rail and ensure they are seated correctly.
3. Reattach the fuel rail to the intake manifold and torque the bolts to the manufacturer's specifications.
4. Reconnect the electrical connectors to the injectors.

5. Reassemble and Test

Sub-steps:
1. Reinstall any components or brackets removed during the process.
2. Reconnect the negative battery terminal.
3. Reinstall the fuel pump fuse and turn the ignition to the "ON" position to prime the fuel system.
4. Start the engine and check for leaks around the injectors and fuel rail.
