Should I see voltage at Air Pump Relay? 850 1997

Trying to replace a water-soaked seized secondary air pump (emissions) in my '97 850GLT. I'm trying the $20 'generic' 12V blower motor hack. Here's what I did:

1. removed old air pump, retrofitted new 'generic' 12V blower. Hooked up input/output hoses appropriately.

2. replaced air pump relay.

Note that I did not replace the SAS ('purge') valve -- I realize that is dumb, but I'm trying to get the electrical part working, first.

When I started the car, I expected to see the 12V blower motor run for about a minute. Nothing. In fact, there is no voltage at the output of the (brand new) air pump relay.

Could the bad SAS valve be causing the air pump controller unit to *not* trigger the relay? Somehow, I doubt it. If that isn't the problem then what do I look at next -- could it be a bad controller?

Any hints/tips from anyone who has been down this path would be very appreciated.

Thanks,
Prof
