    You need to check your fuel pressure. The filter may be plugged up since it runs by adding fuel.

    Have your codes checked and see if any trouble codes pop up. If nothing pops up, I'd do as jim suggested and check your fuel pressure.

    Its supposed to be around 60 I believe. Change the fuel filter, then regulator, then pump, or what in a least expensive to most expensive pattern.
