Details! that is with the key on, and it's the valve under the intake. Engine off and cold.

That valve is under intake level vacuum and connected to the intake near the throttle body (item#20):



It should show 12V with the key on and be open under electrical power.

there's the nugget I was looking for!

But your question makes me wonder: is there ANOTHER purge valve somewhere that you thought I might've been referring to? Should I be checking a DIFFERENT valve?

The operating purge valve at the cannister (item #7 in the top drawing).

Thank You!

Maytag, we can keep our price discussion private (I know that Ferrari guys have lots of money), but it's easiest for me to just put pics here.
You asked about 3 things, but how about the other one that sits forward in the fender? It has two electrical valves and one hose to the charcoal box and another that goes to behind the fuel filler lid.


The fuel line vent valve mount cracked while I was taking it off. I plastic welded it "Stronger than new".



Purge valve under the intake: closed with no power, open with +12v. (test equipment not included)

Perfect.
And you know we're all broke from the cars, right? If we have money, it's spent in more cars. ;-)

I sent you a reply to your pm.
