    UNTIL...open & slam the door, then the indicator lights all come on ( digital mileage read out, trip, etc.) at this point the car will start. there is no interruption during driving..when stop & turn off; same thing to re-start...entire system is dead: no read-outs, ...

      Yes - either loose battery connection - could positive or negative cable - at the battery or the other ends. I'd start right there - check the battery terminals for loose connection / corrosion - should be clean and tight.

      Also, check the negative (chassis) ground cable connection - opposite the battery - could be loose. Once these are OK - then move to the electrical system - checking wiring condition / relays / fuses connections at the panel.

    Lagging power oxy and camshaft changed now wont start
    HELP sportage was starting and driving ok but going though a lot of fuel and lacking power when diving or excelerating. Husband took off both catalac convertors completely still didn't fix. Ran codes that triggered both the oxygen sensor and the cam shaft sendor so ...

      Maybe the timing chain jumped. that would rob all the power and make someone think that the exhaust system is restricted from clogged cataklytic converters. That would also set a camshaft position sensor code.

      I would test the fuel system. Could have bad fuel pump, bad pressure regulator or a clogged fuel filter. Do a fuel pressure test to confirm. What were the diagnostic trouble code numbers. If you list the numbers it would help narrow things down. Did the vehicle run at all with the new cam sensor. If it ran with the old sensor and not with the new one, try reinstalling the old part or getting another sensor. It is possible to get a faulty new part. If your car turns over but wont start, you should start with the basics. Your engine needs fuel/air mixture, compression, spark and timing to function. Make those checks first. Check for fuel pressure and volume at the fuel rail test port. Then do a full compression test. From your origional symptoms I would recommend a compression and leakdown test for sure. Check for spark. Test for power to the ignition coils. Then you check timing. Not just ignition timing, but also valve timing. The cam sensor is a major part in establishing your timing. It controls the ignition timing and fuel injector timing. A fauly sensor will cause all of your issues. I would also check the condition of the timing belt. I suspect that your cam sensor was weak and failing and then you replaced it with a bad new sensor. I had this exact thing happen a few weeks ago. Typically if your engine fails to start and it does not set a DTC or check engine light, it is usually a bad fuel pump. Your engine diagnostics moniter all the sensors for faults, but it cant moniter if there is actually fuel in the lines. That is what you need to check.

    Surging until about 15 mph
    surges from dead stop or at low speed but does not do it in reverse. Doesn't matter if it's hot or cold. 80000 mi. No engine light is on.

      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

    My car shakes in the front around my dashboard and front seats when the car is in Drive and my foot is on the brake but
    stops when i accelerate. Also my check engine light and OD light is on. I goes off shortly from time to time but pops back on eventually.

      The check engine light is located on the dash and stays on if the computerized engine control system detects an engine performance or emissions problem.

There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.
      This step is important - retrieving the stored fault code and relaying this detail - will provide good information to assist in diagnosing and repairing the issue you are having.

      P0734 (Gear 4 incorrect ratio)
      P1624 (Cooling fan relay low circuit)
      P0753 (Gear 3 incorrect ratio)
    • Jimm
      2/28/2014 Jimm
      P0734 = Means incorrect 4th gear ratio. (or tcc problem). Tcc means torque converter clutch. Your car has a shifting problem. It is not shifting into overdrive, (or lock up the torque converter).

      P0753 = Incorrect 3rd gear ratio - similar to the previous code P0734.

      P1624 means that the transmission controller has stored the code and is sending a signal to the pcm telling it that there is a transmission related code

      Have transmission tested for these items; torque converter clutch, lock-up / control solenoid.

    Why are the fuel injectors not opening?
    Gas tank and parts in are new computer replaced ignition switch replaced fuel is pumping but the injectors wont open .

      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 ...

      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.

    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 fail to shift gears, and stale when idle to long?
    My car is shaking bad while idling it will also stale. It has trouble shifting out of first. The mileage on my car is 121972. It happends while driving if I have it in park its ok. I first noticed it last night

      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
