how to fix the fuel injector issue on my Ford F-150 13th Generation (2015-2020)?

Solution

1. Preparation

• Tools Required: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, multimeter, injector removal tool.
• Disconnect the battery to ensure safety while working on electrical components.
• Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.

2. Remove Fuel Injectors

• Sub-steps:
  1. Remove the engine cover (if applicable) by unscrewing the bolts securing it.
  2. Disconnect the electrical connectors from each fuel injector by pressing the release tab and pulling.
  3. Remove the fuel rail bolts using a socket set and carefully lift the fuel rail off, which will also remove the injectors.
  4. Pull the fuel injectors out of the fuel rail.

3. Inspect and Clean

• Sub-steps:
  1. Visually inspect each injector for signs of wear, clogging, or damage.
  2. Clean the injector nozzles with a suitable solvent or ultrasonic cleaner if they are dirty.
  3. Check the O-rings for cracks or deterioration and replace them if necessary.

4. Install New or Reconditioned Injectors

• Sub-steps:
  1. Apply a small amount of engine oil to the new O-rings to ensure a proper seal.
  2. Insert each new or reconditioned injector into the fuel rail, making sure they are seated correctly.
  3. Reattach the fuel rail with the injectors to the intake manifold and tighten the bolts to manufacturer specifications (refer to torque values in the service manual).

5. Reconnect and Test

• Sub-steps:
  1. Reconnect the electrical connectors to each injector.
  2. Reinstall the fuel pump relay and connect the battery.
  3. Turn the ignition to the ON position (do not start) to prime the fuel system and check for leaks around the injectors.
  4. Start the engine and monitor for proper operation and leaks.
