The service center put to much oil on our vehicle when they did the oil change. Right after I left the check gages light came on and stayed on and there was a knocking sound. I was told by a trusted repair shop that too much oil had been put in and there was no oil pressure and no oil going to my engine. I took it back to the original service center and they are saying that my oil pump has gone bad. My question is can the fact that they put to much oil in my vehicle have caused the oil pump to go out.

Yes, most certainly. If you put in too much oil, the engine's crankshaft can actually come in contact with the oil. And because the crankshaft is turning at several thousand revolutions per minute, it can quickly whip your oil into a froth "” like the steamed milk that sits on the top of a cappuccino. Why is that bad? Well, the oil pump can't pump froth very well, and as a result, it can't get oil to the parts of the engine that need lubrication and will also burn itself out very quickly.
