I am probably like you not very familiar with hydraulics and electronics, after pulling stuff apart I am figuring it out though, but what i would do is check your servos on the valves see if they operate, make sure that you didn't accidentally flip a switch on the transmitter that may have turned the pump off. Turn the pump Motor off on your transmitter and move the sticks for each cylinder see if the valve servos activate. Check the electrical connections because they often come loose. Make sure your battery is properly charged. Just check all the simple things first, then we will look at transmitter adjustments, and see if (ESC's, electronic speed control is working. You could have a mix on the transmitter for your different valve openings and on your pump that could be screwed up? Alot of differnt things as i have mentioned but don't be upset, there are alot of great people on the site and we will help yopu through.
