Hey bud, well I had this same problem today what I did was had my wife gf pull on the hood release while I yanked on the up and pop open it went.. if not then try taking a pair of vice grips and grabbing the hood release wire and pull more... becareful though this may break it and you'll be in a worse situation.
Anyways after getting open then spray with wd-40 and make sure you take a wire brush and clean off all the buildup on it.
