You need 3 things for an engine to run: Fuel, Spark or air.
Since air is the least likely, like the previous poster said, check fuel & spark.
You can have pressure on the rail (from build up from the cranking) but have not enough pressure to run. Change out you fuel filter, its $15 and should be done annually anyways. Test your injectors (you can do this with handtools, youtube has vidoes).
Test your sparkplugs (this can be done with a sparkplug tester or manually).
Also check all your fuses & relays, and make sure that you validate your gas hasn't gone bad (or you pumped bad gas into your tank -- this has happened to me).
Check your oil pressure as well (there's gauge for that), chances are its a bad sending unit (only used to show on dash), but you'll want to be extra sure.
