2006 saturn ion 3 won't start on cold mornings-no lights- won't turn over

your battery maybe weak or the terminals of your battery are loose. check your battery charge and clean and tighten your battery terminals.

First of all your service light came on so give it a service then have the service light reset then check the thermastac, water levels and the choke is working properly and all the elecric working parts are good

ck. & see if it's in park or try neutral

there was a lot of problems with the ignition switch and its the same as the chevy cobalt so you can get it at a chevy dealer

You will have to pinpoint what the engine is missing...
- Spark
- Fuel
- Compression

All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the engine to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should.

Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition. Be extremely careful when doing these tests.

my car does the same thing.... i dont think there really anything you can do

LOL repeating questions. Its your ignition switch. its a common problem with ions ( I myself have a 04 ion and had it replaced twice in 3 years) repair is around 400 dollars with labor. Just google "ion not starting in cold weather" and youll get TONS of threads. No recall either its stupid

I have the same car, what i do is turn the key to the start position and hold down the gas pedal for 3 seconds, then start the car. It should start up. If not, it the starter that going, get it checked out. These cars are garbage, i cant wait to get rid of mine.

saturn has a TSB#04-08-45-005D the ignition switches go bad usually when its cold outside and they dont let the car start,common ion issue,,you need a new ignition switch,,not the lock cylinder the switch its a little electric box on the end of the cylinder housing you need to replace that and reprogram the new one to the car,switch is like $40

You may try putting the car in neutral to start it, the light is a "theft" indicator, ignore it. If that doesn't work check your engine coolent level.
