2003 Saturn Ion won't start in the cold weather

I have a 2003 Saturn Ion and I bought it used a few years ago. A few years ago, only in the Winter it doesn't want to start. then 10 minutes later it will almost start, then 5 minutes later as I wait in a freezing car it will start. Usually after that it is fine for a few days, EXCEPT today. It happened twice today with a Service Engine coming up! I have never noticed it before but what is the Problem with my car? Thank You!!!!!

SOURCE: saturn ion,sometimes wont start

The problem is in the ignition - the grease gets thick in the cold and doent turn quite right the first time. everything turns on, but the anti theft system thinks you have the wrong key so shuts off pwer to the starter. it takes 8-10 mintues to reset. That is why it normally starts when you come back later. I have had the same problem and done tons of reseach. Right now my temp solution has been a small heater and an extention cord. I keep it plugged in over night on a medium setting - just enough to keep the inside temp above freezing. I am also researching remote starts because saturn dealership charges $250 to replace the ignition, and a remote start will run about $300. Saturn wont do a recall because they feel it is not a safety hazard. I say that is bull. Good luck!

SOURCE: Car will not start when cold on first try

its the passlock system. The passlock wire is tiny and fragile, and gets disrupted causing your car to think you are trying to steal it everytime you put your key in.

now you can search for this video on youtube, this is where i learned and ever since i did this i have had NO problem with my car starting for the past 5 months.

you need wire nuts, wire cutters, electrical tape, n socket wrench to take apart steering column

first, go to your fuses, find the airbag fuse and remove it just incase you snip the wrong wire. what you do is look below your steering wheel and take your steering column apart. there are a serious of wires electrical taped together that are plugged in. you peel all the electrical tape back exposing the wires, and you find the WHITE wire. its all white, no other color. This wire is for your Passlock system.... this is the wire that got faulty and is causing the car not to start. now what you do from here is kinda tricky, not too bad though.

Seclude the white wire from the rest, so that you are ready to make your cut. Now, what you do is start your car, leave it running, and while its running you cut the white wire in half. then after cutting the wire, turn your car off, and then turn it back on. it should start right up. Then just put wire nuts on the two ends, and electrical tape them back together

The point of doing this is, one is disables the passlock system completely, and two the reason why you do this while the car is running is because snipping the wire with the car running makes the car think that it got into an accident or something, and puts the BCM/car into a "Fail-safe" mode, making it start every single time no matter what.

i thought this sounded insane at first, but after searching for a couple of hours its the only answer that made sense. and now i am the happiest camper in the world as far as it starting

My friends and family who have experience with cars think this is a computer glich of some kind, let me know if you figure this out!
Thanks,

SOURCE: My Saturn ion won't start

sounds like a plugged fuel filter,,,changed it lately?? what might be occurring is,,after turning the engine over for a few minutes,,it just cant get the fuel,,,then after sitting the fuel slowly goes threw the filter,, and you get enough for the engine to start,,,clean filters are a must,,,give this some thought,,,their about 10 bucks if you change it yourself.

I jump started another vechile using my 2003 Saturn ion now it won't start only winds over


Where did you hook up the jumper cables to the ion? I would start checking fuses. Hooking up the number cables in the wrong spot will blow fuses.

My car won't start in the cold weather. I don not have Power Locks or Power Windows. What is the Problem?


That sounds like a battery issue. Batteries have whats called CCA (cold cranking amps) it is the main thing to pay attention to. This is a measure of how much current the battery can provide at 0 deg F. Batteries work better when they are warm, so the colder it gets, the less current it can provide.

Starting an engine requires a lot of current, over a very short time. Meanwhile, cold engines are harder to start, requiring more power to get them going. So look at your battery and its CCA and since u said u bought the car a few years ago. You probably didnt replace the battery yet have u? Batteries usually have a life of 4-6 yrs only. Hope this helped

2003 Saturn Ion will not start when it gets real cold other wise starts fine....do you have any idea what causes this


The same thing happened to my 2003 Saturn Ion. It was a bad ignition switch. I have not had any problem since mine was replaced - it was about $150 and this was four years ago.

2004 Saturn Ion wont start from time to time when it is cold outside.. Like this morning my daughter went outside and the car started right up with the temp outside 7 degrees. She warmed it up for awhile...


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

2003 ion starting after running


Google Saturn Ignition Lock and you'll see that this is a major problem with these cars. I bought a 2003 Ion in May 2008 and have had it in the shop 3 times for starting problems. I just had the entire ignition lock system replaced last month and so far it's been okay. Saturn will acknowledge that this is a problem, but there is no recall or true fix for it.
