    Starts then Dies

    I have a 99 WS6. I have replaced the fuel pump and fuel filter after the car sat this past winter. It will start and then die. If I?m quick enough sometimes and put my foot on the throttle it will stay running til I let off. I?ve swapped relays around cleaned the throttle body. Not getting any codes. Any help would be apperciated.
