Why isnt the car turning over when I try to start it

Hello, Are you saying that the engine is cranking when you turn the key, or that it does nothing. If it cranks but does not start after fueling, I wonder if there is a leak in your evaporative emissions system, or that you got some bad fuel. If it will not crank when you turn the key, it is likely a bad battery or alternator. Let me know exactly what it is doing, and I can offer more information. Do you hear the fuel pump running when you first open the driver door, or when you turn the key to "On" with the engine off?
