Have the gas cap checked. Also, I need you to check fuel pump pressure for fuel pressure drop off. Directions are on our homepage under the DIY section. When you turn the key on, the fuel pressure will build at the fuel rail. When you shut the key, it should hold pressure for a while. If it drops of to 0psi quickly, my guess is there is fuel line leaking near the tank. If it doesn't, then I think you have a HVAP leak (FUMES)leaking near the filler tube, vent. At that point, you will need to have the system smoke checked. I will explaine that when you get back to me with your results.
