Fuel pump info

Can anyone help with some info....

In the process of fitting an immobiliser to my Mk2 cav, was going to break the fuel pump supply but i seem to have come across a problem....

The instructions for the immobiliser say that the circuit i break has got to be live when cranking and perminant live when running, i know it is the latter but is the pump live when cranking or does it just become live when the ignition is on in order to charge the fuel line?

Cheers for your help
