      How are you determining that the injectors are not opening? I would check for positive voltage
      to one side of each injector plug first. also check for any trouble codes stored in the computer.

    Why does my car on idle, shakes, struggles to run, and at random..turns off (faints), but not when I drive continuously?
    When its cold, its ok. Its when the engine gets hot is when the problem occurs. It feels like 2 or one of the cylinders are working for a brief period causing the loss of power, but they are working. I replaced the spark plugs. So I got new ones in there. I replaced ...

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.

      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

      THANK YOU JIMM!!! Your list gave me the opportunity to conduct a process of elimination to pin-point my issue saving me hundreds! When I took it to a mechanic slowly n safely, I asked for a OBD CODE and said there were issues with cylinders 2,3, and 4. So, armed with your list, I drove it to a a discount autopart retailer (mom-pop type) and changed the spark plugs(THROWING AWAY THE BRAND NEW AUTOLITES THAT AUTOZONE ISSUED) and had them replaced with NGK and following your list, cables too. :)

    Crank no start, no fuel pressure and no spark. no codes
    checked crank and cam sensors and they were generating a signal, checked wire harness to pcm and that checked out as well. the 10 amp engine fuse blew and after doing all the stated checks the fuse is still good but just cranks. could there be system to check or ...

      Check the connector and wires for a short at the Vehicle Speed Sensor (on the transmission) and confirm that the VSS is not shorted out because that would blow the engine fuse and / or prevent communication and computer would not function causing no spark or fuel, probably no check engine light even illuminates at key on engine off.

      When the key is turned to "on" do the regular warning lights that also came on in the past still illuminate on the dash panel or is everything dark?

    Do I have an electrical problem?
    I have a 2002 Kia Spectra. It has just over 100,000 miles. I have recently had a tune up (new plugs and wires) and a new alternator belt. The car has had ongoing problems with the passenger side (power) windows not working (the fuse keeps blowing after I have it ...

      The no start issue would most likely be related to the follwing items; weak battery, worn / loose serpentine or alternator drive belt, faulty / worn drive belt tensioner, worn / faulty alternator, corroded / loose battery cable connections (either end of the cables).

      Have the vehicle electrical and charging system tested - for free - at most any local auto parts store. They will test the battery and alternator / wiring / belt conditions with a series of tests; battery load, alternator amperage and voltage output - to determine the condition.
      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. For example, they (RockAuto) list the alternator drive belt from around $3.00, and the alternator from around $106.00 for your vehicle.

      There are several websights that list your codes. try typing in " 0bd2 codes " in your search.
      One sight I use is " actron.com ".

    Why does my car engine hesitate at sporadic times
    I have put in new fuel and air filters, new spark plugs and added fuel injector cleaner a few times. this happens at different engine speeds and temperatures.

      sounds like you car isn't running on all cylinders. it could be from a lot of reasons well 3 no spark no fuel or no compression if it happened all of the sudden it's either fuel or spark. a scanner will tell you

      See if there is ignition spark and use a noid light to see if the fuel injectors are receiving pulse.

      erase the cam code and see if it returns immediately also.

    Kia has no power when you accelerate
    It starts right up, but when you push on the gas the car will move only a little. You slowly push on the pedal and you can go a little more & that's it.

      Check timing belt alignment and check that the crankshaft gear has not partially sheared which throws off cam timing. Do not take this check too lightly. One of the most common causes of this engine losing power like you describe is due to the crankshaft keyway becoming worn enough to allow the gear that the keyway is supposed to keep from moving to slip past the keyway partially or fully. This has the same effect as the timing belt jumping a couple of teeth. The engine will start and seemingly run smooth but has no power on acceleration. One thing that has to be done before anything else though is to plug a code reader in and see what fault codes may be stored. You can obtain a code reader at amazon.com for $20 and can check codes in 2 minutes or less with no experience or tools needed except for the code reader that is.

      No I doubt that the cam sensor is faulty. I'm trying to follow what you are saying but I'm not sure. You are saying - which this statement is throwing me off, " won't make a full rotation almost like a wheezing sound". What do you mean a full rotation? That takes me to thinking you have a weak battery which is not what I think you are saying. Maybe you have a bad timing belt and what you are hearing is the engine rotating too fast because of the loss of cylinder compression from the bad timing belt? Maybe just try rewriting this but say it different.

      The Forte 2.0 has a timing chain, not a belt. No service is needed on the chain until there is a reason to.

      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 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 $ 19.32 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 sensors to operate the car.

      Visit this site and see all the different sensors.
