The problem is not likely to be caused by the Injection Pump itself. The problem is likely caused by either the "Fuel Quantity Solenoid" which is mounted to the Injection Pump and comes with it when you purchase one. It is also available separately. Or the "Fuel Pressure Solenoid", this solenoid is mounted to the back of the Fuel Rail and is responsible for bleeding off excess rail pressure. This part comes as part of the "Fuel Rail Assembly".
Although more common for this concern is a plugged or faulty Fuel Filter. If you are certain that the filter is NEW and not a cheap aftermarket filter then I would start concentrating on the two Solenoids...

The Fuel Quantity Solenoid is the unit with the connector pointing straight up in the following picture..

Make sure the connector for this solenoid is NOT crossed with the PCV Vent Tube Heater. This is common and can cause this problem... The Vent Tube Heater is mounted to the Turbo inlet hose fitting, the connectors are similar and will reach each other....
