2005 chevy cobalt, car wont start ... check

A nice simple answer, you can't. Think of it this way, the car doesn't know you are the owner, and it is there to stop exactly what you are trying to do. You have two computer ECM and BCM, plus the antitheft module and a number of sensors all trying to stop you. All you have to do is the re-learn procedure. Plan B is an auto electrician or alarm / radio installer or auto locksmith.

30 Minute Re-Learn Procedure

1. Turn ON the ignition, with the engine OFF.
2. Attempt to start the engine, then release the key to ON (vehicle will not start).
3. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
4. Turn OFF the ignition, and wait 5 seconds .

I guess you have no knowledge about vehicles
made for the last 35 years, since 1980

We have computers that monitor things & operate
the vehicles

You surely have heard of checking for OBD Codes

You have an Evap System problem to find & fix &
it does not have to be a failed gas cap

Ever read your owners manual,their not of much use,
but you have to get all that down first

Have you tried to do a hard reset? Disconnect your battery for 24 hours. And try it again. This will usually fix a lot of computer malfunctions. Good luck.

Check for any stored engine codes, this may give you an idea of any problems that may cause your complaint. Possible crank position sensor, cam position sensor or ignition module would cause a 'die in flight' situation.

reduced engine power message chevy cobalt 2006,cars sputtering, and when i presses on the gas the car wont move, i can put the pedal to the floor and the rpm's dont bulge

dude you just got stung by passlok, the thing you put youre key in has an attitude if you phone youre chev dealer parts department and tell him the story [leave out the air bag part] he will sell you the the right stuff getting your ignition out is quite a piece of work get literature //after you fix it do this, battery charger leave key on for 10 mins to let the computer get to know the new piece then start it//must do this

I too had this problem, and it was finally resolved after tracing the wires from the BCM to the steering column. A few of the wires needed to be repaired and repositioned.

There are only 2 things you can try to fix this yourself: turn off the engine and open the driver side door (to turn the radio off). Wait 5 minutes, start your car.
If that does not solve it, turn off your engine, disconnect the car battery, wait about 5 minutes. Reconnect the battery (negative pole first - black connector) and try your radio again.

If neither one of these two fix your problem, I am afraid only a GM service center or dealership can fix the problem. The Cobalt is notorious for all kinds of electrical issues.

Thanks for using the fixya forums!

I had the same problem. Have it checked at an checkers with one of their computers. I had a multi misfiring. I changed the ignition module on it. It runs great now.
