either air in the fuel supply, or the replacement pump is very tired. www.fordmondeo.org or www.ilexa.co.uk both have excellent forums where this sort of thing has bound to have been discussed.

First of all, if the pump was tired or there was air in the fuel line, especially on a diesel engine then the car would struggle to run or may not even start. As you have recently renewed the timing belt and fuel pump belt you could refer to the vehicle manual and make sure they have been set up correctly. If this doesn't help then i would advise approaching a Ford garage or similar specialist.
