2000 Saturn SL2 won't start. Bought used-116K miles- from local Toyota dealership only 6 weeks ago. New air conditioner put in by dealership. Was driving ok. Now won't start. Dash lights come on,--makes noise like engine is turning over but won't start. First wouln't start in the morning. Tried it in the evening and it started fine. Then the next day, wouldn't start. Had a second key made when purchased car. Tried the one that came from dealership and the new one--same results.

SOURCE: Car won't start even after new battery purchase

Alternator problem, the alternator charges the battery when car is running, so it has probably died now. Was working at reduced capacity for a while, which is why you were only getting a partial charge for some time. Now you have an open circuit completely as alternator has failed completely, time for a visit to an auto electrician. PS replacing acid in battery with distilled water is not a good idea. It probably was time for a new battery anyway.

try your spare key it sounds like the transponder in the key is going bad

SOURCE: My 1993 Saturn SL2 just failed the Smog Check

change your O2 sensor.

SOURCE: BMW 325xi; 160k; check engine light on-->next day, wont start!

The check engine light is a warning to let you know something needs your attention to be repaired I would try getting a jump. Could be a bad battery. Lets get the battery charged and tested. Cold weather will stop your car from starting if you have a weak battery. You dont need to tow the car just take the battery to Autozone or Walmart to be charged and tested for cca...cold cranking amps
