      Sounds like you have a loose or glazed serpentine belt.

      I looked under the hood and big long belt on the left side of the engine, I believe to be the serpentine belt looked fine. I didn't see anything else that seemed to be out of place or seemed damage under the hood as well.

      DMM, I have a Hyundai Elantra as well, and sometimes I'll have screeching. My car is a 2004 and I have 3 belts (timing, serpentine, and one other). Your belts might be fine, but they sometimes curl up a little on the sides from moisture. There isn't a particular pattern for my belts to screech (whether it is cold or the car sits for awhile unmoved), but you should replace all of them if the noise bothers you that much. I hope this helps.

      Check your serpentine belt. I can't tell from here if a new belt would help or not? Is the belt worn--cracks--splits?

      Usually, that noise is the belt? Did you take it off and look at it? Do the accessory pulleys make any noise, turn freely? I can't think of anything else at the moment.

    There is no electricity, I replaced the battery and still will not start not even a click.
    The car ran fine all day until I had to run errands and the car would not start. There is not a sound like the click you here when the key is turned forward. The starter was replaced about 2 years ago. I purchased the starter from the dealer and installed by the ...

      I would check the fuel pressure regulator. Sounds like its leaking through vacuum line. Causing a rich condition and poor fuel economy.

      How about having a shop do the proper testing to actually find the reason
      for your codes & make the proper repairs ???

      No idea why you would drive more than a day or so after you got your codes
      have to diagnose the codes right away,not drive for two more years

      Can not go to inspection with check light on & violating EPA Emission Standards
      as your doing

      P2273 = Oxygen Sensor Signal Biased/Stuck Rich, Bank 2 Sensor 2

      Possible causes
      - Faulty O2 Sensor Bank 2 Sensor 2
      - Exhaust leaks
      - O2 Sensor Bank 2 Sensor 2 harness is open or shorted
      - O2 Sensor Bank 2 Sensor 2 circuit poor electrical connection

      The downstream heated oxygen sensor (HO2S) is forced rich and lean and monitored by the powertrain control module (PCM). The test fails if the PCM does not detect the output of the HO2S in a calibrated amount of time.
