this a C20xe?

if so, it WONT have an imobaliser..

it will more than likely be the relay, if anything, try tapping it again something.
it's not un-comment for the to just stop working out of the blue

Has the engine loom been cut into for an immobiliser fitted to the car it was previously in?

I wouldn't do it that way, the fuel pump can drag a fair few amps and the ignition switched live doesn't carry a great deal of power to the ECU. Id unwrap the loom near the ECU and see where the wires have been cut for this aftermarket immobiliser and re-connect them as they should be
