Have you checked the diagnostics with a simple Scanner yet? This sounds like an Oxygen Sensor going or gone bad. The Scanner will tell you. If the Scanner says 'all normal', and the fuel system indicates 'CLOSED' status, check fuel pressure with a fuel pressure gauge. If the fuel system indicates 'OPEN', check the Fuel Safety Switch wiring, inside and out, the Fuel System Relay, and the Fuel Pump. Sorry, but the ethanol in the gas is creating an entirely new class of problems.

If it is getting fuel and spark, the only other things it requires is air and compression-You may have an engine so flooded that it won't start in spite of it having fuel now. You can try holding the gas petal to the floor while cranking it, it will dry out the intake and cylinders, but it is best to do this in short spurts and have a battery charger or jumper cables connected to the battery while doing this. Remove a plug to see if it is soaked-if it is, you might want to consider removing all of them and drying them off. While you have a plug, or plugs out you should be able to determine if it has god compression by cranking the engine, the open cylinder will 'pop' as it reaches top dead center if it is alright. Check to see if your oil is unusually high-could be diluded with gas that has washed down the cylinder walls. You can also try to spray some starter fluid into the throttle body, even if the plugs are wet it should try to start if it is getting spark.
