    I've checked the manual and rechecked it, it doesn't list the fuel pump relay at all in any of the fuse boxes. So confused.

    Find the fuse or link that when pulled stops the hum that fuse or link will be labelled that will then confirm if it is the fuel pump running all the time.
    sorry not much more to offer

    I'm going to have to go through them all again, there must be one I've missed. It's driving me insane. I'm resorting to disconnecting the battery over night so as not to drain it

    A bit of research suggests it might be absolutely anywhere - it's black, oblong, with a moulded into the case fixing bracket and plugs into the loom via a flat 7 pin plug.

    What has possibly happened, is that the relay contacts have welded up. If you can open the relay up, you might be able to part the contacts and fettle their faces.
