When the traction control light is on the car wont stay started when it malfunctions and goes off the car runs fine Why?

SOURCE: car won't start

Only a few basic things are necessary for the engine operation 1. Fuel (To be exact proper air/fuel ratio, normally it is about 14/1)
2. Spark (in appropriate moment)
3. Proper timing (the valves should open and close only in appropriate time)
4. Compression in the cylinders (Normal compression is 120 - 170 psi. The engine won't start if the compression is lower than 70 - 80 psi.)
Plus, to start the engine, the battery, the starter and the starter circuit should be OK.

If the engine won't start - there's no magic - one of these things is probably missing. Most often it's a spark- or fuel- related problem, but often it could be very simple things like dead battery.
If the car won't start, check simple things first:
Make sure you have a fuel in the tank, oil in the engine and the battery is OK, follow this link - How to check the battery
Now simply answer the questions, press "Yes" or "No" (If it's blue, follow the link).

- Do you hear the cranking sound when you're trying to start your car? (Yes No )
- When you switch the ignition ON before starting a car, does the "check engine" light come ON? (Yes No )
- When you switch the ignition ON, do you hear fuel pump buzzing sound from the gas tank area? (Yes No )
Before your engine died, did you experience any prior events such as:
- leaving the lights ON overnight (Yes No)
- driving through a deep puddle, or washing the engine compartment? (Yes No)
- trying a jump start? (Yes No)
- having only a little fuel in a tank? (Yes No)
- having had the engine repaired recently? (Yes No)
- the engine was overheated? (Yes No)
- extremely low oil pressure? (Yes No)
- unusual noises such as knocking, pinging, whistling? (Yes No)
- smoking from exhaust pipe? (Yes No)
- strong smell of a gas? (Yes No)

Now, let's try again. Turn off the radio, try to crank the engine one more time, and listen carefully. Is the cranking sounds different than it used to be? If it's different, does it looks like the engine being cranked by the starter too slowly? (Yes No)
Is the engine being cranked too fast? (Yes No)

Hope this may help;

DON'T FORGET TO RATE::

SOURCE: all electrical works lights etc.,car turns over

Most likely a Coolant Temp Sensor & Connector.Under upper radiator hose at cyclinder head.Yellow & Black wires.Hope this helps

SOURCE: saturnl200 was running fine i turned it off and

Check to see if it is getting fuel and spark first.

SOURCE: Traction control system light stays on even when

Hi
check the switch for the traction control, it sounds like a bad earth or poor contact, also check the battery lead from the car battery to the car body. ensure it has a good contact to the car body.

SOURCE: Check engine light came on

Thanks for choosing FixYa and welcome. There are many things that can cause your check engine light to come on. When it does come on, this means the computer has detected a problem with the vehicle. Every car has this system. Anytime it is on, you can usually get a code number off the computer scan. The hookup is under the dash in most cars. You can buy a cheap one for around 50 dollars at most auto part stores. If you do buy one, you may need to find what each code means. If you don't own one or you can't get to one, you can take it to Autozone or Advanced Auto Parts to get your vehicle scanned. Most places do not charge for the scan. Autozone and Advanced Auto Parts do not charge when your check engine light is on. They will be able to scan it for you and give you the codes. They will let you know what it says and what parts you will need as well. if you ask. If your check engine light is flashing, this means there may be internal engine failure. If this is your case, get it scanned as soon as possible. The longer you go with the light on, the greater the chance you have to make the problem worse. Some of the newer vehicles has this system already built in. You will need to know sequence though, to make the code appear
