yeah your secondary air injection is fucked. this is common error on the VR6. I have a spare pump for sale. A new one from the dealer is like $600.

Before you blow cash on a secondary air pump that may not be faulty read this.
You may just have a combi valve fooked or as simple as a broken vacuum line..

considering your from yellowknife your pump filled with water and froze.
check your solenoid.
about a gallon of water per hour.
possible fuse as well.

all the SAI does is blow the rich gas out quicker at start up. It turns off after about 2 minutes and the car warms up. Its not a big deal. I drove around for a year with it fucked and rob is still driving around with his.

Im just deleting mine altogether on my VRT with a frost plug and software that is updated to not even care about it
