      First thing is plug in a scan tool / code reader and see if the tool can establish communication with the vehicle ECM. If it cannot communicate then this most likely either has a bad Electronic Gas Injection (EGI) Main Relay or it has a bad Engine Control Module (ECM) . If it can communicate then see what fault codes may be stored and update the post with the codes.

      The computer will not pull up any information, and the ECM fuse has been checked

      how do you reset the computer and could this be the problem?
      2/17/2013 HouseCallAuto
      What do you mean by "will not pull up any information ". Does the code reader establish communication or not? What words display on the screen of the code reader? Please be specific. If you cannot establish communication with the vehicle computer, you will typically get a error message like "check cable connection" or no communication or communication error or something similar and you will not be able to even get to a screen where it would say if there are codes or not.

    Why can't I use gas pump to put gas in tank?
    If gas is tried to be put in with pump, it vomits the gas back out. Gas can be put in with a small gas can no problem.

      Rarely do mechanics do a rebuild on a clients car engine. Those days are almost gone. It's better to just buy a remanufactured engine and have the shop install it but expect $5000 bill with a 3 year unlimited mileage warranty. Only way to get that down to a number like 2500 to 3000 is to buy a used engine but there is no warranty with a used engine. Nothing wrong with fixing your 08 Optima but obviously you have to really want to keep your same car as many people become emotionally not ready to change out cars.

      okay do you have spark? and injector pulse? and good fuel pressure? and good engine compression?
      check those thing first. I am sure you missing one of this.. let me know if you need more info..

      The fuel pump works when it wants to and the spark does the same. I bought a new fuel filter to see if it was clogged and it didn't do anything. I don't know if its a relay, the throttle body or the ignition

      Sounds like it could be the starter, but check the clutch switch also. Sometimes you can tap the starter and it will work (bad starter).

    Why it wont start but occasionally
    a new battery has been installed , a new timming belt, a crank sensor installed , oil changed and it will run for a day or so and then it won;t start , I have been stranded three times in the last 4 weeks , it only has 48,700 miles on it

      You just said "it won't start" but have not defined what you mean by that. The engine makes no noise? The starter motor is not cranking the engine when you turn the key? Or....., the engine cranks over normally but will not start?

    Why does my vehicle sputter when taking off from a stopped position. Then is runs fine.
    I have 80,000 miles on my Kia but for the last 2 days when I take off it feels like it is not getting enough gas to keep it from sputtering at first. Then it stops and runs fine. It does not do it if I begin moving very slowly.

      First step - have the check engine light or stored fault codes scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific fault code for more assistance.

      Possible Causes of Engine Hesitation or Stumble:

      Dirty fuel injectors (cleaning the injectors often fixes this)
      Dirty air filter (change filter)
      Dirty / clogged fuel filter (change filter)
      Bad MAP (manifold absolute pressure) sensor
      Bad TPS (throttle position) sensor
      Bad or dirty MAF (mass airflow) sensor
      Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
      Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
      Bad gasoline (fuel contaminated with water or too much alcohol)

      Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

      Dirty or worn spark plugs
      Bad plug wires
      Weak ignition coil
      Wet plug wires

      In almost all cases, if the battery light is illuminated with the engine running, the alternator is junk. There are some exceptions but few. The light cannot be on with the engine running. When the light is on it means the alternator is not charging the battery.

      that was my guess..thank you

    Check engine light code 0320, 2005 Kia optima?
    Rough idle and tachometer fluctuates or drops to zero.

      P0320 = Ignition/Distributor Engine Speed Input Circuit Malfunction
      First check the 20 amp ECU fuse in the under hood fuse box. Also check the O2 sensor fuses. If good, next check for battery voltage on the tan/black wires going to the coils while cranking. If good, check for ground of 0.05 volts on the black wires going to coils while cranking. If either is missing, check O2 wires for chafing or rub thru on heatshields or other objects under vehicle. Verify the O2 sensors operation is correct, if so - suspect the ignition failure sensor.

      P0300 = Random/Multiple Cylinder Misfire Detected

      A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.


      A code P0300 may mean that one or more of the following has happened:
      •Faulty spark plugs or wires
      •Faulty coil (pack)
      •Faulty oxygen sensor(s)
      •Faulty fuel injector(s)
      •Burned exhaust valve
      •Faulty catalytic converter(s)
      •Stuck/blocked EGR valve / passages
      •Faulty camshaft position sensor
      •Defective computer

      Possible Solutions

      If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

      If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

    How can I get my 2002 Kia Rio OCB-II O2 monitor to finish resetting? It is "not ready" after weeks & 100s of miles?
    Cleared a code (for very small evap system leak) back in Dec. Three monitors are still "not ready/incomplete". I have been told that the other two won't finish until after the O2 monitor does.
