well you need to have the code scanned to start with but meanwhile do you hear the fuel pump kick on when you place the key in the run position? Have you checked for spark at the plugs?

No matter how complicated our gasoline engines appear with all the smog devices and computer control, they still need the three basic elements to run;

1. Ignition (spark)
2. Fuel/air
3. Compression

As mel said, listen for the fuel pump when you turn the ignition to the run position. That will let you know that the pump is running but doesn't guarantee that fuel is getting to the engine. You should also check fuel pressure at the fuel rail.

Also check your vacuum lines for leaks.
