2.5L single efi, non-turbo auto electric in-tank fuel pump. When I hotwire from positive lead on coil to battery positive, I can then hear the fuel pump humming. when I turn key on with no hot-wire, I dont hear the hum of the pump. does this mean it is bad? when going 25+ mph, I lose power and rpms when i let off the gas. thanks
