My sprinklers will not start

I installed a Rachio 3 to replace a Hunter and I can’t get it to run. Here are the pictures of the unit I replaced and the bed one installed. Any suggestions?

@anayheider - was the Hunter system run right before it was replaced and everything checked out?

Is the water turned on to the sprinkler system? Does water come out of a zone when the master valve and a zone valve are manually turned on at the valve/solenoid?

Is the pump start relay option enabled in the Rachio app?

Do you have access to an ohm meter?
