What would prevent SAI READY w/no codes?

Hmmmmm....a glimmer of hope!

I was not aware of the second running of the SAI pump. This will be hard to hear so I think hooking a light to relay #10/pin 87 should show if it is indeed coming on for round two?

Also, a bad Change Over valve (#3) or bad Cutoff valve (#2) will not throw a code because I am not loosing vacuum? The valve is just not opening to operate within the SAI system?

I should be able to figure out ways to test both valves...as soon as the swelling of my head resides...
