   Hi,
   Secondary or pre-pump is an important part of the system so do not disable it. See that indeed there is power going to the pump with the key off and then see if you can unlug the fuel pump relay to see if it that will stop the pump. If it does you may have a bad relay or short somewhere that will need to be found. Try to get a book and look at the wiring section to see where the system wires and components are located and start the testing and tracing process. This is a bit tough so you may want to have someone with Volvo training take a look at it.
