Default xr3i fuel pump question

Hi , I have a mk iv xr3i cab with efi engine that I,m just restoring.

a couple of months back I was attempting to get it started but no fuel was getting through
as I am now locked down and have time on myn hands I dropped the tank and checked the pump which is working .

The car has no battery on at the moment
if I detach the inertia switch in the boot (which is corroded) and supply a direct 12v feed to the connector that goes to the pump, should the pump run, or do I need to get the battery back on the vehicle?

No it won't as you don't have a circuit, given it has no battery.

You would have to connect the ground of your power source to a good earth point on the car body and then it should run. It's going to be easier to troubleshoot with a battery, unless you purely want the pump to run.
