I have a 200 saturn and every once in a while it won't turn over...battery fine and no engine light

those vehicles are common for starters did two today alone when it wont start try to tap it with a hammer it on the back side of the engine under the intake if it starts replace starter

Best case scenario: Your battery is dead or almost dead.Worst case: The engine has seized and you have to replace it. Do the dash and interior lights stay on or turn out when you try to start the car?

The voltmeter should only go as high as 14-15 volts when the engine is running. I would check for a poor connection between the battery and starter.

Done cars have a kill switch if they are low on oil. Check your oil. If the oil is good, it may be the ignition switch.

If the engine fires up for a second or two with starting fluid then the fuel pump is weak.I would check the fuel pressure and if its not within the specs then replace the pump and filter.

Hi Vernon, There could be a number of different reasons why your vehicle is failing to start. The battery voltage could be dropping during start and become unable to engage the starter motor to turn the engine. You can check this by trying the key with the head lights switched on. If the lights become very dim, you'll need to check the battery, meaning clean the terminals and then try to start with a jump from another battery. If you achieve start up and it fails again the following morning, you will probably need to replace the battery. There could be a problem with the starter relay or a loose contact for the starter motor, most lik3ely the one connecting to the soliniod. It would be good to know some additional information, such as does a clicking sound come from the starter when engaged? Is there a perceptible drop in voltage output when the starter is engaged? does the enine turn at all? Try what I've suggested and if that does not solve the problem answer the questions and let me know anything else which you may think is relevant. Regards John

this is an article showing you why the battery light on.

Only things that would cause that are, most likely, the Idle Air controller, the Throttle Position sensor, or possibly a vacuum leak. If it continues, you will get a check engine light eventually.

A wrench symbol is the equivalent to a check engine light. Take your car into a mechanic and let them diagnose the error code the engine light is storing to help diagnose the problem.
