There were not that many Pure's sold that had power steering but it was an option on 451's. If your car has power steering, you will see a steering wheel icon in the right hand cluster display when the key is turned to position @1.
To diagnose your concern with locked steering, first place I would look is the steering shaft coupler. If the coupler seems okay, I would disconnect the outer tie rod ends from the steering arms and then turn the steering wheel. If the steering wheel turns easily and the rack goes back & forth, I would look at the upper strut bearing plates but this would be a rare occurance. I have heard of steering shaft couplers coming apart and binding the steering wheel.
