First thing I would do is check the fuel pressure it should be between 50 - 60 psi. Unless you have a scan tool to command the fuel pump on then this should be done while cranking the engine. The computer commands the fuel pump on for 2 seconds when you turn on the key, and turns it off unless it sees a ignition reference pulses.
Another thing you can do is take off the fuel cap and put you ear near the opening have someone turn on the ignition while you are listening and you should hear the fuel pump come on for the 2 seconds, make sure the key is off for at least 30 seconds before turning it on. If you don't hear it come on at all then you need to make sure it's getting power and ground. Comment on this answer after you have tried that and I can give you more info.
