Repaired Frozen Pipe with new bonnet and poppit but sprinkler system wont come on?

Hi, I just replaced my bonnet and poppit because it cracked during a freeze here in houston, TX but now when I go to turn on the sprinkler system during its first zone it wont come on? None of the zones wont come on? Theres only small bubbles of water coming out on some of the sprinkler heads but nothing else? What could be the problem? Please help?

I would like to ask if any trash got in the back flow discharge side? Maybe you did not get the back flow preventor put together right, you should have it inspected when finished with the repair. When I take apart the backflow to make the same repair you mention, I also open the water side and let any trash get out of the device. Is the check valve below the poppit and bonnet kit O.K.? Even though you can stop the leak in the vacuum breaker, it may not be serviceable due to the check valve having trash in it or being damaged or old.
