I am sorry that you have not been helped yet. I just came online and saw your question

Low voltage condition due to a weak battery can definitely cause low pump pressure issues so this should be addressed to begin with by charging or replacing the battery as needed.

If still an issue after charging or replacing the battery, I suspect that the new pump is defective out of the box and you will need to return it for another

Do all vectra 1.9 cdti pumps push same pressure (what is the pressure) could it be any other fault ie injectors sensors or regulator or is it most likely a faulty pump?
