    I need some help. Car quit going down road, I have changed both crank sensors the camshaft sensors and the starter. The battery is showing 12.4 volts. I did to jump it. It sounds like the bendix not coming out. Any help out there. I did check codes I had a camshaft code but it reset.

    Sounds like a bad starter. Take it back to where you bought it and get a new one.

    If you are able to turn the engine using crank then a starter should be able to too.

    Starter pinion spins, but does not engage the ring gear? Where did you get this starter?

    The new starter runs just like the old one. I had the old one tested and it checked good. The bendix did not come out as fast as I though it should so I put a new one on it. Is there something that will not let it turn over as fast as it should. The battery is 2 years old but I charged it and even jumped it still on go.

    I am still unclear as to whether or not the starter pinion is engaging the ring gear and not turning the engine or is the pinion just spinning and not engaging the ring gear?

    sheared the teeth off the starter - not likely -
    or flex plate - also not too likely -
    bad bendix - more likely -
    possibly a broken flex plate - saw one from a N* that cracked through at the mounting bolts - starter spun the broken flex plate but not the motor - you wouldn't believe the noise it made!

    Flex plate center has come apart. Not common, but not unheard of. A thread and pictures somewhere in here or Northstar within the past 6 months.

    Requires complete transmission removal. No other way. BIG bucks.

    Re: 2002 sls problems starter turns motor dont rotate

    You really need to inspect the starter, remove intake.

    The starter solenoid is the relay operated magnet that flips the gear in & out onto the ring gear. The starter drive or gears reduction has failed.

    You may have a bad magnet or power source to the magnet(the small wires)or the solenoid relay may be defective.

    These are the easier less costly repairs. Starter replacement is the more reasonable remedy for any starter defect.




    The worst case senerio is

    #1-the starter mount in the block broken/cracked block...

    #2-the ring gear is broken/cracked at the crank flange which is more common

    #3-ringear teeth section broken out & repairable but requires engine/trans removal for all 3 problems...
