Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, multimeter, basic hand tools.
Safety Warnings: Disconnect the battery to prevent electrical shorts; ensure the engine is cool before starting work.

2. Remove Engine Cover

Sub-steps:
1. Use a socket set to remove any bolts holding the engine cover.
2. Carefully lift the engine cover off and set it aside.

3. Access Fuel Injectors

Sub-steps:
1. Disconnect any electrical connectors from the fuel injectors by pressing the release tab and pulling straight out.
2. Remove any retaining clips or bolts holding the fuel rail in place.
3. Gently pull the fuel rail away from the intake manifold to expose the injectors.

4. Inspect Fuel Injectors

Sub-steps:
1. Visually inspect each injector for cracks, leaks, or carbon buildup.
2. Check the O-rings for wear and replace if necessary.
3. If using a fuel pressure gauge, verify that the pressure is within specifications as the injectors are being examined.

5. Reinstall Components

Sub-steps:
1. If no issues are found, reattach the fuel rail ensuring injectors are seated properly.
2. Reconnect electrical connectors to the injectors.
3. Reinstall the engine cover and secure it with bolts.
