The problem is your Fuel Pressure Regulator. this is really common on newer cars to go is the way you can check to see if that is the problem. Locat the fuel rail on the engine. find the little round valve looking thing on the fuel rail that looks like it has a vacume line hooked to it. This is the Fuel Pressure Regulator. All you have to check it is pull off the vacume line going to it and if there is any fuel that comes out of the top of the valve or out of the vacume line this is the problem. there should be no fuel comeing out of it or the vacume line. and this will not cause a check engine light to come on. The regulator could run from $50- 130 depending on. Hope this is the Answer you were looking for
