Chevy 2009 cobalt will not start; when the key is turned to the start position nothing happens (no clicks or other noise; headlights do no dim). Everything else seems to work.

You said "nothing happens" and if you mean "nothing" then your solenoid is (at the least) not charging; otherwise you should hear a click

Solenoid does not click. Check the solenoid and I am getting 12.6 volts from the battery to the solenoid.

you answered your own question - the solenoid isn't engaging because .....

Hold up. That's a colbalt take it to your dealer ASAP. There are way to many recalls on these to even start to list them. But one is for the ignition switch. Failure to have recals taken care of can lead to serious injury or death.

Please have this car checked out ASAP. Hell if recalls have not been taken care of yet I would call dealer and have it towed to them.

I'm sure it's part of the many recalls that are listed for the Cobalt.Have it towed in, ask nicely for a substitute car, and don't pick it back up until it's ready.

dandyoun already got somebody at GM interested - way to go dandyoun

Not sure if the symptoms of the ignition recall include failure to start, but that is a possibility, otherwise I would suspect the starter is at fault if everything else is working. Any GM dealer can look up your vehicle's serial number (VIN) and tell you if it is subject to any other recalls and if so whether the work has been done.
