Cerbera 4.2 fuel pump

Hi all,
My car has been off the road for years now and after replacing the coolant and adding new pipes from ACT and a new battery I attempted to start her up.
So I get the engine cranking over nicely but the fuel pump does not prime when I press the black button.
I've checked the fuel pump relay No.4 and that clicks fine and has continuity across the terminals when I apply 12v.
I didn't think it would be the immobiliser as this is meant to cut both starter motor and fuel pump. Also I use the touch fob and the flashing light goes out.
The silver key (master) seems to be fine as the ignition does not come on at all with it off, then comes on when switched on.
I pressed the ignition on and then check to see if there was voltage at the pump, there was not. Should there be 12v to the fuel pump all the time or would it only be a few seconds? If so then maybe by the time I get round to the pump, the volts have dropped off.
Also I have checked the roll over switch, I found the rubber was pushed up but I don't think it was active. I pressed it all back together and no joy either.

Hopefully someone has some other things I can check or bypass to try and diagnose this issue.

Thanks
Alan

The immobiliser has 2 circuits, one for the starter and one for the fuel, so still could be worth bypassing it to check.

Do you have any info on bypassing? I don't want to go making it worse haha.
