What year is your car?

Things to do: 1) check timing like the others said - may be able to just look through the inspection hole on the cam sprocket cover, 2) spray something flamable into the intake while you're trying to start it - if it fires then you know it's a fuel problem, 3) check the fuel pressure in the fuel rail - on mine I just remove the nut on the end and use an adapter to my fuel pressure gauge (not expensive tools), 4) remove spare DME relay from glove box and install.
