The ECU commands the SAI only after engine has cooled down to certain temp. I also had a MAF sensor go bad earlier in my ownership that prevented the SAI to startup. The engine ran smoothly but no SAI. Replaced MAF and ok. I have confirmed also that you can force SAI once it comes on to go ready without driving the car. Many have doubted this to be true and stated car needs to be driven.
Have you checked the pump itself by jumpering 12v directly to the pump? Think it's only 2 wires to a motor.
