Power steering pump broken while installing new main pulley
I have a quick question.
I had the front pulley changed out on my car as the stock one started to separate like on so many other C5s.
power steering system was working before anything was touched.
after taking the car off the lift and test driving the power steering pump is now broken and had to be replaced with a new gm part, now all is well again.
What are the chances that it just broke and it was a coincidence?
Who believes that this has to do with correct procedure of removing and replacing the steering rack and the way the fluids were primed and bled ?

Possibly incorrectly bled pump allowed air pocket to burn up pump. Nose of pump shaft physically damaged when incorrectly removing pump pulley (the OE C5 pulley is "solid" and must be removed to get at a mounting bolt behind pump). Possibly cross-threaded hose fitting threads (on pump) when re-attaching line(s). Possibly cross-threaded pump shaft nose when re-attaching pulley. Any/all combination of the above.
I would suspect a bleeding issue first. I would also be willing to bet you were not shown the old pump, and if you go back now to ask to see it, it will be "thrown out already".

The pump was not removed. The pulley he is referring to is the crank pulley. OP has a habit of leaving things out of his stories.

I'm curious to hear opinions how possibly a power steering pump can break while changing out the front main pulley. I know the steering rack has to be removed to do it and it shares the same fluid with the ps pump

As I said, I would suspect the fluid/seized/bleeding of the pump first.
I was looking at the date on the link post.

Also this problem happened immediately upon start up which means the pump would have had to "burn up" while on the lift not running. The only other way is if the mechanic didn't fill the reservoir before starting the car. If the reservoir was full even air in the system would not cause the pump to go bad in such a short time. But after reading all the OP's posts and the mechanics replies I think the pump was on it's way out when brought to the shop.

Been working on cars and trucks for many years and the one thing I've always found prats don't always warn you before they brake don't care if there 7years old or 7days old it can happen at any time. Car can be running great one minute stop and now it won't start. seems like we always have to find someone or something to blamefor it just my 2 cents worth.

it doesnt matter when it happened
Im trying to understand if its really possible for it to happen, the power steering to go out the same exact time the steering rack is worked with.
looking for opinions as you can see I didnt mention any names in this thread another guy did

You're not trying to understand anything. You're looking for forum members to unwittingly back up your extortion claim. That's why you leave out most of the facts, both in this thread and the other.
This forum has been great for me. I've saved so much money, gotten such good advice and met some really great people. I absolutely hate to see it used by someone to advance a questionable agenda and repeatedly misrepresent their story. You sir, represent everything that is wrong with the internet.
