I unhooked wires from fuel pump. Hot wire reads 12.58 volts with battery reading 12.6. Engine not running. Changed ground of fuel pump from frame to battery. Still reads about 8.5 volts when I touch leads to fuel pump while it's running. If I unhook ground wire and check the hot wire while it is connected to the pump (pump is not running) the wire reads 12.58.I am a terrible electrical person so please forgive me if I am ignorant sounding.
