Question about Ford F-150
Looking at the wiring diagram - the controls for the pump are...
Fuel Pump relay (already changed)
EEC Power relay (already changed)
There IS a slight chance of the can-purge purge solenoid being failed - and keeping voltage to the pump.
Remove Wire 31 (cut temporarily) on the EECM to verify this is NOT the case. (the wire is GRY/Yellow)
If the pump stays running still - the EECM is the culprit.
