A CESSNA 152 COLLIDED WITH A FENCE DURING A FORCED LANDING. AT 4,000 FT MSL, THE CFI SWITCHED THE FUEL SHUT OFF VALVE TO THE OFF POSITION TO SIMULATE AN ENG FAILURE. THE STUDENT PILOT SWITCHED THE FUEL SHUT OFF VALVE TO THE ON POSITION. THE ENG DID NOT REGAIN RPM. THE CFI THEN 'DOUBLE CHECKED' TO SEE THAT THE STUDENT SWITCHED THE FUEL SHUT OFF VALVE TO THE 'ON' POSITION. THE ENG BEGAN TO FIRE AND THEN QUIT. THE CFI THEN CHECKED THE FUEL SHUT OFF VALVE AGAIN ALONG WITH THE MIXTURE CTRL, MAGNETOS, AND ENG PRIMER. AT 2000 FT MSL THE PROPELLER STOPPED TURNING. THE CFI ENGAGED THE STARTER IN AN ATTEMPT TO RESTART THE ENG. THE CFI OVERSHOT THE INTENDED LANDING AREA AND SELECTED ANOTHER ROAD AND LANDED SHORT OF IT. THE ACFT STRUCK A FENCE AND NOSED OVER.
