Default 8s ecu into jap

Fitted the ecu into my import,

Car wouldn't start, (thought it wouldt)

The fuel pump does not prime up

Went to change transponder box around the barrell from donar car, aswell as the key to match ecu

But I have no where to plug this into on the loom

Does this mean I need change the whole loom?

Iv swapped cam and crank wires over,, and moved the fuel pump pin to number 17 for immobiliser postion it says on the pin out diagram,, but won't start still as fuel pump will not prime up,,

Has the key from donar car 97uk needed to match the ecu to let it start?
