If all that passes we are left with two things: either the twist connection for the controller wire to valve was bad or the solenoid is bad. Or you may think you have a bad starter relay. 4 volts means you need to buy a new battery. Keeping the probes plugged in, turn the relay right side up. Starting system troubles may be caused by poor maintenance, or just wear and tear.
