i have talked to a few people and they said it could be my "vent control valve" is stuck shut. Any feedback on this would be appreciated and if so any clue where that is located?thanks

I don't have a Cobalt, but the vent control valve that I think they are referring to should be connected to your air filter system. I could be wrong but there is a valve door on my trucks air cleaner ducting that opens and closes. Mine currently is always in the open position because it doesn't really matter in my truck. There is also an exhaust gas container that contains charcoal for excess fuel vapor flow but this shouldn't be related. I can't say anymore. The only other valves that are related to gas but maybe not in your situation is the EGR (exhaust gas recirculator) valve on my S10's intake manifold.

#11 of 46 Gas tank overflows when filling by mikeof48

My 2004 5 cylinder Colorado has 75,000 miles on it. About two months ago when I was filling it with gas, the gas didn,t shut off and it overflowed. I've caught it doing this a couple of times since. Also, when I start it after getting gas, it cranks like it doesn't want to start. It does start but takes a long time compared to other starts. The service engine soon light is on and my mechanic says it's because the new fuel cap doesn't seal properly because the gas tube is bent due to the gas pump nozzles resting on it. This I understand but don't understand why it overflows and starts so hard.

This doesn't sound right. As far as I know, if the gas pump doesn't shut off it's because THE GAS PUMP'S nozzle isn't set correctly, allowing it to run on after detecting "backflow". That's a safety measure designed into the pump.
 
If your gas cap isn't sealing correctly, I could see how that might cause a hard start, as the tank won't pressurize correctly. However, I doubt that the weight of the nozzle alone, would deform the filler neck. On the rare chance that it did, it wouldn't be a hard job to replace the filler neck. It isn't part of the tank. It's a seperate piece that attaches to the truck's bed with 3-4 screws, and a short length of rubber tubing connects it to the tank. If the dealer won't warranty it for you, it shouldn't be an expensive fix.
