It is unlikely that your SAI pump is bad. It is more likely a pinched hose (super common), blown fuse (behind driver headlight), or bad valve.
All of which are cheap fixes. a lazy mechanic would just diagnose the replacement of a pump which is expensive and annoying to replace. I would do some tests to see if the pump getting elctricity, the pump is turning on, if air flow is happening, diverter valve is functioning, and if the solenoid valve is working before I would pay someone.
The SAI pump is an emission mitigation system and is not needed for car functionality but makes the world a little cleaner. Most states require the system to qualify for a tag, so you better check before ripping it out.
