Check for spark/fuel/air. The air part is pretty easy, it's the spark and fuel part that you need to look into. Check for spark at the plugs. You can push the valve on the fuel rail to check for presence of fuel, but you really need a fuel pressure gauge to measure it. And as always check for codes before going too far beyond the basics.
