If it has spark it should at least start for a few seconds. Are you sure you have spark AT the spark plugs if you pull a plug wire and hold it close to a good ground, you might have to stick a screwdriver in the plug wire boot then hold the screwdriver shank about 1/2" away from ground and it should have a nice blue/purple spark....

Install a fuel pressure gauge on the test port on the fuel rail and let me know what the pressure is when trying to start it please.
