Fuel pump running all the time is not a good sign. Unplug the big multi-pin plug from the ECM (computer). If the pump then stops running the computer is probably bad.

thanks. Well this model has a low pressure and high pressure pump...the ft tank has been eliminated.. as soon as I switch the switch from rear to ft. pump on fuel tank shuts off.. but the one on the fuel rail keeps running..
