On the ignition side of things, lack of signal from either the cam or crank position sensors could be causing your no-start. On the fuel side of things, injector poppet nozzles or fuel pressure regulator could be bleeding off fuel pressure. Your next step might be to verify fuel pressure at the fuel rail on the manifold (rather than just at the pump), and presence of spark.
