First, Does it work when you press the manual buttons?

If not, fix the plumbing.

Next, Does it work when you manually hook power to the
solenoid wires?

If not, replace the valve or check the wire connections.

Next, Does the relay provide 12 volts when activated
and 0 volts when not?

If not, something is wrong with the relay, the
controller or the program.

Next, Is the connection good between the relay and the
solenoid?

There really isn't much more that could be wrong.

Go through your system in a systematic way and I am
sure you will find the problem.
