2003 Saturn Ion Q&A
2003 Saturn Ion Question: car won't start
You may have a fault with the anti-theft system - is the theft/security light flashing when your car won't start. You could also have a weak battery or corrosion on the battery cables causing a low voltage condition. - Russ
HI, I know I am a few months late on this,but the starting problem is normal for the saturn ions. Replacing the ignition does not work. The only solution is to cut the white wire in the ingnition harness while your car is running. Go to youtube.com and type in the search white wire cut ssaturn ion. It will explain more.It is a defect from saturn.when it gets cold or kind of cold that wire has to stay at a certain voltage and it does not and causees your computer to not recognise your key and will not start. Try turning the key to just before it starts,when all tthe dash lights are on,then off again,do it about 3 times and the wait 20 minutes,the car will start,but ut will no doubt happen again,so the only real way and cheapest ay is to do the cut of the white wire. scott 2004 saturn ion-2 owner - GRIGGLE2
Faulty security systems should be correctly repaired. Cutting wires as per an online video is not a cottect repair. Most issues with GM passlock systems are caused by faulty passlock sensors which are in most cases part of the ingnition lock cylinder. I would recommend to have the anti-theft system on your 2003 Saturn Ion properly diagnosed and repaired. - Oakman
This issue is caused by excessive grease in the Ion ignition switch shipped from the factory. You can fix the switch yourself using this site as a reference http://moontaj.com/passlock or hire a professional to replace it. It will be $30 for the part and way too much for labor. - Visitor
