I have lost track of how many teams I haved helped with a valve not firing that turned out to be be 12v being supplied to a 24v solenoid, even when it was working at one time. A very common error that is often due to following an out-of-date KOP wiring diagram with 12v wiring. If you did some rewiring work, definitely check this out. If there is any doubt about whether the valve is getting power or functioning, use a power supply or two batteries in series to provide 24v directly to the solenoid wires. If the valve functions and the breakout led's are lighting, the you have a power wiring error.
