Let's get this straight , when you turn the key to the start position ,what happens ? Does the starter engage an spin the engine ? Or not . If you what help you need to give better descriptions . You turn the key on an the dash light come on , do the warning light's go off after a few seconds ? Is the anti-theft system light on an then goes off . Do the headlamps work , an shine bright ? Viewing a wiring diagram of the starter electrical circuits to see what it takes to make the starter spin the engine would also be a good idea . It just so happens the starter is computer controlled .
Circuit Description
Moving the ignition switch to the START position signals the body control module (BCM) through discrete inputs from the ignition transducer that engine crank has been requested. The BCM verifies that theft is not active and sends a serial data message to the engine control module (ECM)/powertrain control module (PCM) requesting engine start. The ECM/PCM receives a 12-volt signal from the park/neutral position switch or clutch pedal start switch notifying that it is safe to start the engine. There is a splice on this circuit in the fuse block-underhood that supplies power for the starter relay coil. The starter relay coil control circuit is then grounded by the ECM/PCM closing the switch in the starter relay suppling 12 volts to the S terminal of the starter. Ground is supplied through the engine block.
Your best bet , have it towed to a qualified repair shop.

I am not a mechanic and have had no problems with my 2005 Ion-2 but at msn/autos I see that these can exhibit a starting problem because of the ignition switch which they recommend replacing. The part is around $40 & the labor is 1 hr.

replace your pvc vavle then have your cars underbody washed

When this happened to mine it ended up being a bad door switch. The alarm, dome/map lights and electric door locks are all connected to the door switches. It cost $65 for diagnosis, parts and labor at Saturn of South Burlington VT

check the wires going from the driver door into the kick panel there should be a rubber thing around the wires and cut it off and the wires usualy break and loose connection
SOURCE: 2003 Saturn Ion will not start. Security lock is on.
The fix for this problem is well known, so is the cause. GM needs to step up in my opinion. You can fix it yourself if you're willing
