    Why my car doesn't start
    Lights and other electrical systems work. When I turn the key I hear a fairly loud, very rapid clicking sound. I have had no previous problems with starting or the battery.

      Sounds like a weak battery or a bad connection to the battery. Look at the terminals on the battery for corrosion or one of them being loose. Also check the ground where it connects to the car frame or body. If you can't find it there you may have a loose connection at the starter or a bad starter post or ground.

    Grinding sound when I start to car.
    The grinding is not loud in park, if I put it in neutral it gets really loud and when I put it back in park it stays loud. When I put it in gear the grinding goes away. What could be the problem?

    Can a newer engine transmission be swapped into my 2005 Tuscon?
    Poor fuel economy is the issue. It runs fine.

      Have you done a tune up and replaced the fuel filter with a fuel system cleaning? How's the air filter? These are major factors in fuel economy. Check Engine Light on? How are the tires?

      Typically, the oxygen sensors (O2 sensors) are replaced in pairs or sets - due to mileage / age / wear considerations.
      The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the oxygen sensors from around $37.00 (each; upstream and downstream) for your vehicle. In your case, the 2.0L engine has only two (2) sensors - easily located and replaced.

      Utilize the 'How-To-Guides' on the AutoMD website for the specific steps to replace the oxygen sensors.

    Looking to buy a 2003 Hyundai Elantra, but there is a strange ticking noise
    There is a used model that I am looking to buy- new brakes and a new clutch. It is a 5 speed manual and drives perfectly other than a loud clicking noise. I want to say that it is coming from the engine, but I'm not positive. As the RPM climbs higher the noise ...

      Buyer beware...any ticking noise - especially from the engine area usually is not a positive indication. Maybe related to; valves / engine / bearing wear - each is expensive to fix. Find another, less noisy vehicle to purchase. Understand, that without a personal, up close inspection - there is little accuracy in diagnosing a noise issue via the internet.

      Also, consider taking any potential used vehicle for purchase to a local, trusted repair shop in your area for a thorough inspection - before any purchase. There are lots of used car buying guides published which will help you examine a used vehicle; performing your own inspection / what to look for and what to avoid - be sure to take advantage of these books as well. Check the local library and auto parts stores.

      DO NOT SKIP THIS TEST..

      Check the vehicle for fault codes to see if there are any sensors were involved to the malfunction of the engine.

      1.Local auto parts stores such as Autozone ( not in California) or Advance Auto parts or Pep Boys will scan and retrieve any diagnostic trouble codes ( dtc ) stored in the powertrain control module for free of charge..

      2. Amazon.com has the code reader for less than $ 18.00 dollars + shipping
      Autel MaxiScan MS300 CAN Diagnostic Scan Tool for OBDII Vehicles

      3.Re-post the dtc's in here " answer question " for further assistance.

      Note: we need the dtc's to identify the sensor, there are a dozen different ELECTRONIC sensors to operate the car.

      Visit this site and see all the different sensor definitions.

      Powertrain Control Module (PCM)
      Throttle Position (TP) sensor
      Mass Air Flow (MAF) sensor
      Intake Air Temperature (IAT) sensor
      Idle Air Control (IAC) valve
      Engine Coolant Temperature (ECT)
      Heated Oxygen Sensor (HO2S)
      Camshaft Position (CMP) sensor
      Knock Sensor (KS)
      Vehicle Speed Sensor (VSS)
      Crankshaft Position (CKP) sensor

      P0300 Diagnostic Code - Random Misfire
      P0301 Cylinder 1 is misfiring
      P0302 Cylinder 2 is misfiring.

      Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or un-metered air getting past the airflow sensor, or an EGR valve that is stuck open.

      Note: first check the vacuum leaks.

    Warm air from air conditioning
    109500 miles. Had my air conditioning system checked for leaks and freon is charge. Also had a relay replaced. Mechanic said that the clutch on the compressor may need to be replaced and cost over $1100. Today very warm and the air conditioning going down highway ...

      Had the same issue with my car. Check your cooling system. Your car might be trying to stop overheating condition by shutting the a/c off. Make sure there are no leaks around the hoses or the radiator itself. Also check and see if the thermostat is working correctly. Mine was stuck closed which I think lead to my radiator busting. After replacing my radiator and thermostat my air is blowing cold again

    Why does my oil pressure light come on only when I come to a full stop?
    Oil light and Temp rises when I come to a full stop. Light goes out again and temp drops a bit when I accelerate again. I'm afraid my car will overheat again. I have a new radiator in it because the last one popped on the highway (it was ugly) Any ideas?
