I use to have this problem as well. I got pretty good at hitting the hood just above the grill about 4-5 inches from the center, on the drivers side, with the palm of my hand while someone pulled the release. I also had the interior piece the the release is mounted in off one time and it worked perfectly.
The problem, which I discovered on this board, is that the latch is binding against the side of the either the front or the back of the female side. You should be able to tell which by looking at the marks made from strikes. If you bend it away from where it's binding it will open correctly.
