    Check battery condition, if good... check starter motor.

    Could be solenoid on starter motor.. suggest to rebuild unit if it's failed.
    It isn't too expensive.

    Hope that helps.

    I've got the same problem. Sometimes is OK,but sometimes I've got it. Many
    people said,that the is cube with connectors witch is swift to think where
    You put your key (ignition switch??-I don't know english very well:(( ).

    If battery or solenoid were out, the lights on desktop must turn off, or
    light more darkness,..but if the lamps were OK, the problem is with ignition
    switch.

    This is almost always the starter motor. You can verify easily if you
    connect a volt meter between ground (any exposed metal on the body or
    engine) and the big terminal lug on the starter. You should see
    something in the area of 12V, have someone turn the key, if it only
    clicks and the voltage doesn't change drastically then the starter is bad.

  6. Yes, we call that the "ignition switch." It is a common failure, but mostly
    in the running position rather than the starting position. Mine was a lot
    worse when cold, and the dashboard lights didn't come on when the switch was
    bad.

    Follow the ground casble from the battery to the bolt where it connects
    to the engine behind the power steering pump and replace the lug
    connector. Then relocate the cable to the rearward bolt on the power
    steering bracket so that it isn't flexed by the sway bar.

    If you are getting a click the obvious thing is a weak battery. Check
    voltage at the battery. Should be close to 13V. Before you start
    replacing parts check and clean all the connections, especially the
    battery ground. Also check for corrosion at the battery cables.
