You were correct. Outside by the valves, something had "eaten" the ground wire from the box to the valves. I fixed it and it works now.
Reason I said my neighbors is working, down here in FL we use/have reclaimed water for irrigation, and sometimes we run out. Therefore I have had this same issue where I would run my sprinklers and nothing would happen/no water. This time, all the neighborhood sprinklers seemed to be working...hence why I believed it was my system vs. a water supply issue.
