I see what you mean Todd. It's not listed anywhere. And nary an image of it exists.

Question;

If you remove that solenoid, is it ported on it's base to the cannister. I'm assuming it is.

Todd, I'm thinking you could remove that defective solenoid, mcgiver the cannister to accept a outlet line, buy a 'new style" solenoid purge valve, install it in the "return to engine" line and it might work. Seems the two lead solenoids do not signal open or closed to the pcm. It's probably the vacuum being sensed (or not sensed in your case) downstream somewhere when the purge side opens.

Perhaps the very similar (minus solenoid) later design vapor can would fit in that body hole?  https://www.amazon.ca/Canister-%E2%80%8E911-261-Compatible-Roadmaster-Commercial/dp/B0B2NJD1XW

It looks to be that the the 94 Buick Park Ave (and others?) was a one or two year design can. The fuel vapor inlet looks to be integral, with the vacuum line "to engine" being solenoid ported into it. Did they do away with that style solenoid to streamline the part better across more models? The numbers for the later style are across most all GM's 95-99.

I wonder if mine is unique as 94 was "OBD 1.5" whereas the plug is OBD 2 but the codes are OBD 1". I believe the PCM needs a certain resistance from the solenoid to determine if it's working. A wrong resistance creates a wrong voltage at the PCM and it creates a Quad Driver fault. I may be out to lunch but that's how I understand it. I think I'd need to make sure a replacement solenoid has the proper Ohm rating as mine. Obviously I can't measure mine as it's possibly defective. I'll have to reread the diagnostic tests in my shop manual to confirm but I don't recall seeing any ohm rating mentioned.
