had the same problem with my truck when I first got her... have someone sit in the car holding the hood pop latch out/pulled. Then you go up to the front and try to get your fingers/something in between the hood and the bumper. A few thumps may be required. If this is a suddenly occuring problem, check your cable from the interior latch to the hood latch. Also, with someone holding the latch to the open position, lower the hood slowly into the latch, making sure everything is lining up. Luckily, hood latches are way easy to replace. If the problem has been around for a while, check the rubber stoppers/springs in the latch for wear and tear. Good luck.
