Turn on the key and measure the fuel pressure, or at least press the little button on the end of the fuel rail and see if there is pressure (But really, you want to know the pressure, book says 45 or more PSI is what the design calls for).

If the pressure is really low, the injectors wont' fire properly. I mean, face it, you need three things to start the car:

• Air. Air is drawn in by the engine turning over, if the timing chain is intact to run the vavles, you almost gotta have air
• Fuel. THe pump has to be providing enough pressure for the injectors to act.
• Spark. The plugs have got to be firing.

The last two items, the plugs and injectors, are driven by the "Powertrain Control Module". If the fuel pressure is up and the cam and crank sensors are telling the PCM what the engine is doing (how fast it's turning over and the exact timing of the cam and crank), then the PCM can fire plugs and injectors.
