how can I tell if my Ford F-150 13th Generation (2015-2020) fuel pump is bad

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the vehicle battery negative terminal to ensure safety.
• Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.

2. Remove the Fuel Pump

• Access the Fuel Pump:
  • For in-tank pumps, remove the rear seat or access panel to reach the fuel pump assembly.
• Disconnect Electrical Connectors:
  • Carefully disconnect the electrical connectors from the fuel pump.
• Remove Fuel Lines:
  • Use a line disconnect tool to detach fuel lines from the pump assembly.
• Unbolt the Fuel Pump Assembly:
  • Remove the retaining bolts or screws securing the pump assembly to the tank.
• Lift out the Fuel Pump Assembly:
  • Carefully lift the assembly from the tank, taking care not to damage the fuel gauge sender unit.

3. Inspect and Replace the Fuel Pump

• Inspect the Old Pump:
  • Check for signs of wear, damage, or debris in the pump.
• Install New Pump:
  • Place the new fuel pump into the assembly, ensuring it is seated correctly.
• Reassemble Fuel Pump:
  • Reattach the fuel pump assembly and secure it with the retaining bolts.
• Reconnect Fuel Lines and Electrical Connectors:
  • Ensure fuel lines are securely connected and the electrical connectors are firmly attached.

4. Test the System

• Reconnect Battery:
  • Reconnect the negative terminal of the battery.
• Prime the Fuel System:
  • Turn the ignition to the ON position to prime the fuel system, allowing the pump to build pressure.
• Check for Leaks:
  • Inspect all connections for fuel leaks before starting the engine.
