Question about 2003 Saturn ION

1 Answer

My 2003 Saturn ION won't start

When the engine is cold there is a vibration in the engine and the MIL indicator/light flashes off and on ( like it is firing on 3 cylinders ) after the engine warms up. The MIL indicator/light goes out & the vibration goes away. The engine won't crank up now.

The vibration is a sparkplug that is misfiring. I would start by replacing the spark plugs. Also just in case add a can of dry gas to eliminate any possible water problems.

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.

One is front of the cat, and one after the cat of the exhaust.
The OBD Scanner should tell you which bank is producing the error.
Bank one is the front one.

SOURCE: What does it mean when the dashboard indicator

that is your 'check engine' light.if it stays on, one or more sensors on your engine has sent a 'trouble code' to the on-board computer.a diagnostic code reader needs to be connected to it to determine the cause.

Why does check engine light blink when I accelerate?


Hi Ced ,
The malfunction indicator lamp (MIL) is located in the instrument panel cluster. The MIL will display as either SERVICE ENGINE SOON or one of the following symbols when commanded ON:
Check engine ! The MIL indicates that an emissions related fault has occurred and vehicle service is required.
The following is a list of the modes of operation for the MIL:
?€¢
The MIL illuminates when the ignition is turned ON, with the engine OFF. This is a bulb test to ensure the MIL is able to illuminate.


?€¢
The MIL turns OFF after the engine is started if a diagnostic fault is not present.


?€¢
The MIL remains illuminated after the engine is started if the control module detects a fault. A diagnostic trouble code (DTC) is stored any time the control module illuminates the MIL due to an emissions related fault. The MIL turns OFF after three consecutive ignition cycles in which a Test Passed has been reported for the diagnostic test that originally caused the MIL to illuminate.


?€¢
The MIL flashes if the control module detects a misfire condition which could damage the catalytic converter.


?€¢
When the MIL is illuminated and the engine stalls, the MIL will remain illuminated as long as the ignition is ON.


?€¢
When the MIL is not illuminated and the engine stalls, the MIL will not illuminate until the ignition is cycled OFF and then ON.

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.

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.
