It use to be the rule of thumb with carburated engines that if you have fuel, spark/ at the correct timing , and compression it should start.
How ever with these fuel injected engines you need fuel/ at the correct pressure. Get a helper and have them spray a little starting fluid into the air intake while you crank it. If it fires up for a moment then your fuel pressure is too low. Put a pressure gauge on it and check fuel pressure. These engines need at least 30psi on the fuel rail to start, and that is low. You should see about 35-40 psi on the fuel rail.
