    engine not turning over

    ok so i was bashing around today all going good
    after 3/4 tank noticed the idle playing up a bit
    brought it in and it stalled

    went to start it with my EZ starter and nothing just a click.!
    click click click every time i went to start

    both lights are on EZ starter but nothing.

    did some testing tonight and its strange still only get the click sound
    it dose not even sound like its going to start
    both lights are on to start at first then,
    motor light is on but glow plug light is not, then try again and the motor light turns off
    and the glow plug light turns on.??

    can one can help me out or had a similar problem or know what is going on here

    its a revo 3.3 5309 only run around 10 tanks through it so far.

    thanks guys

    When you say the engine won't turn over does this mean it seized or it's turning over but it's not firing up? If it's seized then it sounds like it could be a broken conrod or something like that and the clicking noise the gears on the easystart slipping under load as they try to turn the engine over.
    IF the engine is turning over but will not start check the one-way bearing which could be slipping and any possible air leaks.

    its not firing up at all.
    when i brang it in it was running really rough then stalled.
    when i went to start again over and over i took air filter off and it was back firing out the carb.
    i may have put the wrong wires back in EZ start,i just swapped black and red around and it got the EZ motor to spin,
    but no sign of it firing up at all.
    its like the motor seized , but i don't know how out of the blue this could just happen..
    i perform after run maintenance every run.

    i cleaned the bearing too but still no luck..
    no air leaks either.

    Changing the red and black wires over will just change the direction of the easystart motor,turning the oneway bearing the opposite way. i.e the pin rollers in the bearing will not bite on the starter shaft and will spin freely. I think you will have to strip
    your engine apart to see what's going on inside it.

    Yer that's what I thought. Just spinning other way.
    I think I will have to pull it apart tommorow and see what's going on..
    I really don't know what I'm looking for though..

    Once you've taken the engine take the easystart and the header off you will be able to take the back plate off the crankcase.
    slide the easystart shaft out .check for any debris (bit's of metal) or to see if the conrod has broken away from the crankshaft which happens. The conrod should also be attached to the piston using a wrist pin. you could try to turn the engine by turning the flywheel anti-clockwise you should see the conrod pushing the piston up and down.
    If that seems ok then take your piston out and check it over. also check to see if your front and rear engine bearings are not
    seizing.

    Take off the cooling head and look to see if there is any damage,ie- cracked piston. Sounds like the piston rod has broken.
    My first 3.3, the rod wanted out and put a hole in the bottom of the block, second one tried to exit through the piston. I'm waiting for some warm weather to break in the 3.3 I had sitting on the shelf. Traxxas has replaced both engines,great product support, I think after this engine, I'll sell the one on it's way to me from Traxxas and get something else.

    If you can't turn the flywheel by hand, or can, but it stops at a certain point and wont turn anymore, it is most likely the rod.

    Maybe I missed it, but will it turn over with the glow plug removed? If it will, it could have just been flooded. If that's the case, place a rag over the cooling head and let it spin for a seconds to clean all the excess fuel out. As far as the red/black wire go, the red should be on top.

    won't turn over with or without glow plug.!
    not flodded tried that too.!
    I'm thinking its the EZ motor somehow
    it hasn't got the power to spin.?
    anyway i called up LHS to ask some questions and he said it sounds really strange too.
    taking it there for some testing today
    will update later with the outcome.

    i can turn the flywheel too, so don't think the piston is seized.

    If you have a multi-meter probe the wand ports and see if you get 7.2v to the ones for the starter. If so, it could be that your starter motor is done.

    When you say it won't turn over WITH or WITHOUT the glow plug. . . . . . . . . . . .

    Internal damage.

    Hate to say it but I'd put money on it since the same thing happened to my 2.5r.

    A piece of the piston broke off and got stuck in the crank.

    Do yourself a favor and open it before you go to the LHS.

    If the battery is charged, and you are down to pulling it apart anyway, remove the motor, the easy start form the motor, and then give the easy start a try (just keep you finger on the one way bearing). With the easy start on or off, you should be able to turn the motor by hand at the flywheel. If it turns easy, you should be good, if not, like said above, you prolly have some internal damage.

    Do a quick test and move the connectors a little on the ez start motor. Mine had a fault that would cause it to just click and not do anything. Just for giggles.

    If the engine is fairly new, I would send it into Traxxas and have them look at it. I can't gaurentee that it will be replaced... but this similar thing has happened to two of my 3.3's, shortly after brake in, and both have been replaced.

    How about an 8mm wrench? Not the one that comes with the truck as the metal is too soft but a true 8mm wrench.

    New motor in..
    Won't crank over..
    Piston sticking at top of sleeve.
    And EZ start Gos into protection mode I think because it stops.
    This is brand new motor.??
    I lubed it up..??
    Do I have to heat it up for first start.?
    I didn't have a problem with the original motor like this when I bought the revo .???

    Unbelievable guys.!

    Not unbelievable, it’s actually very common.
    All new engines should be pre-heated prior to starting.
    No slipper/tall gearing/power = broken parts.

    What he said. Put some after run oil down the glow plug hole to help loosen things up. Heat the engine with a heat gun or blow dryer then fire it up. Make sure your wand battery is fully charged and let her rip.

    Ok I am kind of having the same issue, I was trying to start it today and it was turning over just really cold so it would not fire then the EZ start just stopped turning if I mess with the plugs it will turn but still wont start Im thinking it is just flooded with a combo of stale fuel. The last time I ran it I didnt get all the fuel out of the lines and it sat for 2 weeks so I am thinking that is contributing to the factor. I do have a question should I ditch the EZ and go to pull start? Any ideas and suggestions will be appreciated.

    It won't matter if you leave fuel in your truck you'll snap your pull starter I would say ez start is better for you.

    Still no start for me guys.!!
    Heated up engine
    Everything connected right.!
    And nothing.!!
    EZ motor not making a peep.!!
    It's like it's not even on the truck
    Just dead..
    Maybe the EZ motor burnt out whilst
    Trying to kick over the old motor.??
    I can't belive this..

    All of your connections are good correct. Even the yellow ground wire to the motor mount.
