Jimm 2/17/2014Not likely - about the only way the steering pump could have been damaged would be if the steering fluid were not added to the system prior to the engine start-up for the first time.
The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
In fact, they (RockAuto) list the power steering pump from around $103.80 for your vehicle.
HouseCallAuto 2/17/2014Possible yes but just as possible for the pump to fail not from the mechanic causing it. Also, ps pumps are not so sensitive that if they are run without fluid that the pump will be destroyed in minutes or less. Ive been fixing cars 38 years and this is a myth in my opinion because I have never seen it happen, even though I would warn a client to fix asap to avoid this as a possible event.
