I have a Craftsman 2200 psi power washer, model 580-752342.  It was working fine, but leaking a lot of water from the input (hose connection) and output (high pressure hose connection) pipes when under pressure.  I got a new hose washer and a new o-ring for the pressure hose, and now it doesn't leak on either side.  Neither does it work.  If the gas engine is turned off and the water turned on and the high pressure hose disconnected, water flows through it with full water pressure from the hose.  If you start the gas engine, all water stops flowing out of the high pressure fitting.  Anybody have a diagram of the pump, or an idea of what might be wrong?
