If it's getting gas and a spark, it should start. There are three things needed for combustion, gas, air, ignition. Not many things will interfere with the air so I'd try a different means of determining whether or not it's getting gas and spark. Remove one of the front plugs, put the plug wire on it and ground the base to the block. Have someone turn the key and see if you get a spark across the plug. My best guess based on so little information is a bad coil. Check your fuel pressure if the spark is good. Check your fuses for parts to the fuel system.
