Ah, HA, now verify the signal to the valve from the relay. It should be a
square wave, on/off/on/off, several times per second, 12v/0v. You will need
a graphing multi-meter to do this. If that's not what you then replace that
control relay after verifying it's input and ground circuits. Pull the
cover off of it. See evidence of heat stress under a hand glass?? Replace
it if you see rosin weeping from solder joints or purple colors on ground
planes and terminals or a matte, porous finish on any of the solder joints,
or corrosion anywhere at all.
