    After putting gas in my car, it sputtered and died. Now it won't start.
    Mechanic checked fuel pump, and its working. Checked coil pack and crank sensor. They are working. Need some ideas of what else might be wrong.

    After putting gas in my car, it sputtered and died. Now it will not crank at all.
    The problem is definitely not the crank position sensor or coil pack, because those have been replaced and it did not help. Fuel pump is working fine, also.

      The turbo failed-- & you kept driving-- until the turbo sucked
      out all the oil & ruined the motor

      So, less than two miles ruined my motor, and yet others drive with a knock for hundreds of miles?

      Big difference from an engine knock due to a cylinder misfire or other reasons
      & you driving with no oil in the motor

      You drove two days after the oil light came on & the turbo was red hot

      Why is your mechanics advice not sufficient ?

    Timing advice. Lining up the cams and crank without the aid of the old belt
    I was preparing to change the timing belt so I pulled the timing belt cover off. Was lining up notches by turning crank with the belt on. As I was turning, everything slipped. I thought I had stripped the crank bolt, broke my ratchet or my socket. Upon inspection, ...

      Now you first wash down the front of the motor with mineral spirits or brakleen

      Then you get a kit that includes an instruction booklet,water pump,timing belt &
      all required new pulleys

      With the instructions & some You Tube Video you will be fine & learn alot

      In the future-- watch the videos & paint the gears & belt-- before removing the belt

      In your case it was stripped & gears most likely in the wrong place

      Just to be safe- do a cylinder leak down test- to be sure the valves
      were not hit & damaged & all cylinders seal properly

    Why won't my check engine light come on when it is obvious that I have some serious engine problems?
    This is an edit to prev. info. Check engine light only on briefly w/o enough time to use OBD. How do I diagnose problems w/o any idea where to start in my particular problem? Lots of posibilities but can't just start buying parts one at a time and hope I hit on ...

      You do not need a check light on to have problems

      You will have data with or without dtc (codes stored) if you
      were to use a professional scan tool to look at it

      If you have a code reader they all have different capabilities

      What you want is to road test & see if the Emission Monitors all run
      There should be about 13 & most cars & inspection stations only
      look at 8 If they fail then you have work to do

      No you do not buy any parts until you learn how to perform component testing
      & find a failed part No problem found,no need for parts Your correct there

      The coolant should be 50/50 or 60/40 proper coolant & distilled water
      Is the coolant in the system & plastic tank staying in there,if not then maybe a
      head gasket as you said

      In all you have said what exactly is the problem?

      Have you done a cylinder leak down test-for valve issues
      A coolant combustion gas test -for head gasket
      Checked for a worn & jumped timing belt
      How about a worn out & partially blocked converter
      How is the fuel pressure & volume,does it hold

      If your issue or problem is not monitored then no check light
      If you have a head gasket failure but it doesn't over heat (Yet) then no MIL Lamp

    Think I have a blown head gasket
    Get a strong smell of antifreeze inside car when heater turned on. Also, cooling fans will not come on unless the A/C is turned on and then I get heat in car. Occasional 'pop' like small misfire or backfire. Feels like it is going to stall while driving - ...

    While driving vehicle feels like it is losing power and going to stall.
    Problem presents itself after a few miles of driving. Repeatedly pressing gas pedal seems to make engine run normally but for only a couple of minutes then repeats the problem. Occasional 'pop', like small backfire. Starts well and runs great between the power ...

    Why does my car not start after refuelling?
    After putting gas my car does not start. When I turn the ignition switch the car tries to start but it doesn't turn over. Eventually in order to start I press on the accelerator and the car starts but immediately dies (by stalling). What I need to do is keep ...

      Chances are it's the EVAP purge solenoid stuck in the open position causing the intake manifold to be "flooded" with fuel vapors after refueling

    Why does my car hesitate when I step on the gas?
    Sometimes when I accelerate, it seems like the car stalls or pauses a bit before it wants to get going. It kind of chugs for a second and then gets to the right spot/gear. Especially if I haven't warmed my car up, or I'm going up a hill from a stop. Also, It hasn't ...

      The power steering is most likely not the cause of the main problem you're having. However it's possible the power steering and transmission both use the same fluid, so make sure the leak is coming from one and not the other. Check for any stored codes. Report them here. Hesitation can be caused by numerous problems to name a few:

      Faulty ignition system
      Clogged fuel filter
      Weak fuel pump
      Vacuum leaks
      Dirty air filter
      Dirty maf sensor
