I am well aware of this problem. I had to figure it out myself after my shop kept replacing the pump and vacuum switch that activates the 2 main solenoids. These solenoids are opened at start up to take the air from the pump and inject into the exhaust manifold. The water in the system comes from a defective solenoid( broken diaphragm). I replaced the drivers side one from Rock auto and it was great for a couple years until the passenger side went. Tricky expensive job but still saved a bundle once I found the problem. The pump will kick in continuously and the lights will dim when problems start.
