How do you land kickflips?

I'm having TONS AND TONS of TROUBLE with kickflips. I can ollie, shuvit, fakie shuvit, pop shuvit, manuel, boneless, casper, bert slide, rail stand. What happens when I fo kickflips is that the board will always shoots front of me and it will do these things. The board will always shoot in font of me and it will make the full rotation and I'll land with my front foot only or with no feet or it will over rotate and my front foot will land on the board upside down. Another thing that happens is that the board will go vertical when I do it. Another thing thing that happens tha I'll have hard time popping the tail it will either spin back side or shoot out in front of me and make the full rotation. Also the board will shoot behind me. Even when land kickflips which is very rare is that I'll land with my feet close together with my back foot on the tail. These problems also occur when I try them moving so skaters who can land this trick on the bolts on flat ground and rolling, please give your BEST tips on how I can fix ALL my problems with kickflips on flat ground and moving and only answer if you can help with problems if you can. THANKS!
