If you give us the info on the 4 cylinder, that can help others who might be looking into this in the future.
Ok, on my 151 w/ Rochester carb. it has the same choke setup on the carb as most other vehicles... the difference is what actually gets the power to the choke pulloff...
I had mine go out on me earlier last year, and figured out that there was this little box on the passengers side wheel well (like right below the stock jack mount and between that and the charcoal canister, I'll get a pic later). Well, that box, from what I could tell (no parts stores could figure out what the heck it was) is a simple ignition relay. When the engine starts, the relay is activated, allowing the full 12V to go into the choke pulloff on the carb. But, like I said, no one could figure out what it was, so we tried various relays with different setups inside, most either didn't get the power to the choke, or actually didn't let the engine turn off when I flipped the key off! Those ones required us to actually unplug the relay for the engine to die...
However, I did eventually find one that worked... conveniently off of some year of Pontiac Fierro (go figure, since this is the exact same engine) which is a Standard Motor Products, Inc. RY144 Relay
Now if you have seen any of my other posts about choke problems... I simply decided to stop screwing around with it, and installed a manual choke.
(The reason I think it stopped working is upon adjusting it every season we finally got it to not sit in there correctly, thus not grounding properly... but I didn't care to buy a new choke pulloff so lol)
