Have you tried checking the Camshaft position Sensor? The camshaft position sensor, in conjunction with the crankshaft position sensor determines the timing for the fuel injection on each cylinder. The cam shaft position sensor is a half-effect device triggered by a magnet on the camshaft. Also, it sounds like it could be the one-way valve. See, fuel is drawn through an inlet screen into the pump, flows through the one-way valve passes through the fuel filter and is delivered to the fuel rail and injectors. The pressure regulator maintains a constant fuel pressure to the injectors. The injection quantity is is determined by the length of time the valve is open. Hope this helps
