Check the fuel pressure regulator, it is located under the black cover by your intake hose. The regulator is at the end of the fuel rail, a good way to check that it is faulty is to remove the vaccum hose connected to the intake manifold, if there is any raw wet fuel then it is bad and needs to be replaced.
