Their is a lot more to turning a DM4 pump up, than screwing the leaf screws down, the roller shoes, need to shorter for 1 thing. Your pump probably has a delivery valve stop leaking. That will leak the fuel back in the pump that should be going to the injectors. Take it off & let a pump shop help you out.  GOOD LUCK
