    Z20let Ring Gear / starting

    Hi, I have a zafira gsi turbo and i have an issue starting it when its hot, it just sound like the starter is spinning an not engaging. I have just had a brand new starter fitted and still have the same issue.

    When trying to start the pulleys are not turning so obviously the fly wheel isnt being turned, the car will bump easy when it fails to start.

    What i would like to know if its possible the ring gear is slipping when the engine is hot? As i take it they are strectched on and not bolted / built in?

    The car never fails to start when its cold or warm, only when its had a bit of hard, the temp gauge remains normal and ive also replaced the temp control sensor.

    Please any help would be great, im running out of ideas

    the engine will still turn over if the crank sencor is ****ed,as you have changed the starter then i would say you are right and seems to be the ring gear but tbh i have not heard of this happening b4 but always a 1st

    I'd be inclined to change the crank sensor first off.

    The engine would still crank over even if the sensor had gone wouldnt it? Why does it only happen whilst hot?
