I checked the repair manuals and there's desperately little on the SAI there. Something that I did notice was a reference to a ground strap to the secondary air pump bracket. If that's missing you may have a break in the circuit that drives the pump.

Yes, this is a huge ground connector right next to the SAI pump with a 13mm nut on it.You probably have to disconnect and move this out of the way when R&R the SAI pump.
