It wouldn't cause your pump to blow lol. I had an SMG problem and since I had an aftermarket stereo they assumed it was that because when they got the fault codes, there were communication errors. How do you know your pump is done? What symptoms do you have?
Btw for me it had nothing to do with my stereo. It was because my steering angle position sensor was throwing codes since my alignment was really off.
