why does my Ford F-150 13th Generation (2015-2020) fuel gauge not work

Solution

1. Preparation

• Gather required tools and parts.
• Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

• Tools Required: Fuse puller or needle-nose pliers
• Locate the fuse box under the dashboard or hood.
• Identify the fuel gauge fuse using the diagram on the fuse box cover.
• Remove the fuse and visually inspect it for any signs of being blown.
• Replace with a new fuse of the same amperage if necessary.

3. Check and Repair Wiring

• Tools Required: Multimeter, electrical cleaner, and electrical tape
• Trace the wiring from the fuel sender unit to the instrument cluster.
• Use a multimeter to check for continuity and resistance along the wires.
• Clean any corroded connections with electrical cleaner and secure loose wires with electrical tape.

4. Inspect and Replace Fuel Sender Unit

• Tools Required: Socket set, fuel line disconnect tool, and safety goggles
• Safely relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
• Disconnect the fuel lines and electrical connector from the fuel sender unit.
• Remove the fuel sender unit from the fuel tank.
• Inspect for physical damage; replace the unit if necessary.
• Reinstall the new fuel sender unit, reconnect fuel lines and electrical connectors.

5. Reassemble and Test

• Reconnect the battery.
• Start the vehicle and check if the fuel gauge functions correctly.
• Monitor for consistent readings and ensure no warning lights are illuminated.
