If you have a rainsensor( this is unknown at this time), it is understandable that you could manually turn on the system at the controller/timer and get no results. It is possible that if you had rain and have a rainsensor, that your rainsensor is doing its job and preventing the system from coming on. This doesn't explain why individual zones come on or don't come on, and that is where you may have individual issues as cut wire, poor connection with wire nuts perhaps not water proof connectors, or solenoid or diaphragm problems.

let us know.

First off, find a genuine image host. Facebook isn't it, not when your every 'image' leads to a secure sign-in page. Greenlawn and Rain Jet have nothing to do with each other. And yes, the Greenlawn valves can have issues. Hard to replace, when they're the angle valves. By the way, there should be a nut or screw on the valve 'bonnet' that is for manual operation, unless they modified their design.
