I think the pumps are coded to the ECU. They talk to the ECU and the ECU tells the pump  the settings , so either change the pump for the original or change over the sensors/control unit  on the pump if possible .

There were some old posts about the same problem and changing the pump was the way to go.  (I think )

There's an immobiliser over the fuel cut off solenoid on the fuel pump, it's paired with the ECU. You can get around it by cutting the casing off that houses the immobiliser and replacing the solenoid with one that is switched by the ignition. There are quite a few posts elsewhere about this with more detail on here & elsewhere.

Not sure from your reply what the problem is?
One way to check if the solenoid / pump is working would be to take a pipe off from one of the injectors, put the pipe end in a plastic bag then turn the engine and see if you get any fuel in the bag.

There are quite a lot of threads with pictures about the solenoid, try searching for "1.9d solenoid".

For example:

I think you need a decent manual mate? The solenoid is on the pump and is shaped like a cut off solenoid tbh
