2000 Ford Explorer gas gauge stuck in full

1. Inspect and check fuses
2. Locate fuel pump connector by the fuel tank and disconnect does the gauge move?
3. If it does drop tank
Inspect fuel pump module, float and float rod for damage. If fuel pump module, float and float rod are okay, go to next step. If fuel pump module, float and float rod are damaged, replace fuel pump module and retest system.
4Connect ohmmeter between ground and fuel pump module signal lead (Yellow/White wire). Slowly move float rod from full stop to empty stop. If ohmmeter reading slowly decreases, check fuel gauge circuit or replace fuel gauge and retest system. If ohmmeter reading does not decrease, replace fuel pump module and retest system
