If you have voltage between the ground and the Large slot(neutral( and not the small slot(hot) then polarity would be reversed.
You can't "be certain" it is connected to the Line side, you have to be sure. Good Luck
Many newer GFI's will not trip and reset if no power is going to them.
In fact, I know the outlet in question is the last in the series because it only has one black and one white coming in.
