Fuel at the test port doesn't mean anything as far as no-start conditions. The fuel pump will run for one second after you turn on the ignition switch. After that, when you press that test port, fuel should spray almost up to the hood. If it just dribbles a little, the pump isn't turning on.
The most common cause of no-starts is the crankshaft position sensor, however, that will cause no injector pulses as well as no spark. Since there is still spark, that sensor has to be working. That leaves fuel quality and fuel injectors. The camshaft position sensor also used to cause loss of both spark and fuel, but on some newer engines it just causes the injectors to not fire.
The place to start is by checking for diagnostic fault codes. Cycle the ignition switch from "off" to "run" three times within five seconds without ever cranking the engine. The codes should display in the odometer readout. Only the fuel system is not monitored by the Engine Computer so to know for sure if pressure is high enough, install a pressure gauge on the test port. Expect to see somewhere between 45 and 50 psi.
