Spring check-up revealed a blown underhood fuse for AIR pump. I have replaced it, but am curious what a not working AIR pump would do to the engine besides affecting emissions. May it also affect driveability, fuel economy? Chances are it is bad and will blow the new fuse soon.

It does ZERO far as driveability or fuel economy.
I would just pull the relay for it.
If you don't need the pump for inspection I'd yank it and all the related crap too.

GM even did a TSB to "disable" the air pump, they didn't remove it, but instead just made it non-operable and slapped a sticker stating so on the car(s).

Thank you. Sure it blew new fuse right away. Screw it - I'll leave it alone. :)

A lot of people just remove the AIR pump. That cleans up the engine compartment. I sell an inexpensive sticker for removing the AIR pump that you put on the radiator mount. It isn't legal to remove the AIR pump, but a lot of people do it anyway. PM me if you want to buy a sticker.

Thank you for the offer. It is not a priority right now. Never noticed the related fuse was blown. Will leave the AIR pump alone for now since it does not affect anything.
