2002 Ford Explorer Sport Trac XL 4.0L MIL Lamp on
Here is my question... Fuel pump in this returnless system is always commanded at 100% even when its already running with too much pressure and rich. I know the pump module is bad but Im not sure that would explane why the pump is comanded 100% on all the time...
