First thing I would check is to see if you are getting gas to the engine. Turn the key on, but "not" to the start(crank) position. You should be able to hear the pump run for about 2-3 seconds as it primes the fuel rail. Then check the Schrader valve up by the throttle body to see if fuel comes out. Use a rag to catch the gas and watch out for your eyes, wear goggles. Is the starter turning the engine over fast enough?
