If a car's ABS pump is running all the time even when the keys aren't in the ignition, could it be caused by a shorted out relay??

We think that a relay (which didnt have a cover on) has shorted out on the body or something...

If not the relay what else could have caused it (bar the fusebox, thats fine)

 

is it the cos? ive had same problem,was the pressure switch on the pump.same as all sierras with abs.5 quid from a scrap yard to find out
