temporarily switch the new valve to the red wire at the valves (to test new coil/valve) with zone 1 on.
IF this works, then either
1) you're not properly turning zone 2 on at timer (zone 1 may still be on ??)
2)green wire is bad somewhere in the middle
3) zone 2 is 'burned out' on timer (can happen if wires accidently short while zone is on) - try zone 3 lug.
4) if none above fixes, throw away timer/valves and buy more pebbles like those under the valves to REPLACE all of grass in lawn; problem solved, never any more sprinkler problems, and lower water bill
