Power steering pump or pump pulley?

My car was making a clanking sound (like a bolt had come loose and was jumping around in my motor) while in idle. I had 3 different people tell me it needed a new timing job, so I had the timing done (yes, the whole kit), only to find out that wasn't the problem. When the job was done, and we went to start it up the same noise was there, but it had more of a scraping sound now and could smell burning rubber. Now I'm being told it's my power steering pump but I'm having a hard time believing that when I had zero issues with my steering before (no noise when turning wheel, no fluid leaking, no resistance in steering wheel). Could it be something else like the power steering pump pulley making the noise? I've taken the belt off to test if the noise is still there when I start it and it's not but I do still smell burning rubber and it terrifies me that the person that's been doing work on my car(not a certified mechanic)has done something wrong and that his advice about it being my power steering pump is wrong. Please help!
