I would just go back to the basics. Start the car do the three complete cycles. Check all the hoses and make sure they are in the right configuration. Make sure you have plenty of fluid in the reservoir. Top hydraulics You tube video is great! Go through Pizza Guys video and thread again. You may notice something out of the ordinary. I've even had the trunk latch issue before so have someone put a little weight on it while you try to raise/lower it.
Good luck!
