2 zones not working

Trying to fix a 4 valve system. 2 of 4 are working properly. The 2 that are not working wont turn on with the auto timer, however they will operate when I turn the bleeder or solenoid. I replaced the solenoid on both valves, re-wired all 4 zones at the box, still no luck with those 2 zones. I also checked connections at the control panel. Any suggestions?

Sounds like a broken wire somewhere in the field
Do you have a multimeter?

Ohm out that valves by touching the particular valve and the common, if you don't get a reading or an infinite number then you have a broken wire somwhere

As a tech, my next step would to simply wire trace out the line to where the break is, this may be more difficult for a homeowner. I know you can rent wire tracers, it may be easier to install a new wire from the controller to the valve box?
