    Hi I have intermittent problems starting my car. When I turn the key
    to start the engine, the lights and dash lights all come on and then I
    get the X through the car light flashing on my dash and the car won't
    start. after 10-15 tries I might get lucky or if I turn it really
    fast it will start. When it does start however, it takes a couple of
    turns bc I think the fuel pump was cut off?

    One weird thing... I had this problem before and it went away but when
    I took it to get fixed, the guy disconnected my battery and it came
    back. Is it inter-related? My battery is newer. about 1 year old?

    Any ideas?

    btw does anyone have a FR Headlight Wiper motor for sale?

    Does it happen with both keys? If not, it could be the chip in one of
    the keys is gone.

    The antenna ring, the receives info from the key chip is a weak point.
    There's lots of info on this at groups.google.com, search on "antenna
    ring"

    This happens with all my keys actually... sometimes it starts and
    sometimes it doesn't

    But I don't get why it's inconsistient. If the antenna ring is "weak"
    then why does it work well sometimes and sometimes not? Is it weak to
    begin with and something is interfereing with it? I talked to the
    dealer and they said it could be the antenna ring or ignition coil.

    I think it's the antenna ring also.

    You need to see if there are any DTC's set which could help you narrow
    down your failing part if it is the ant ring it is a little bit harder
    then Volvo's other lines this takes about 2 hours to replace as the
    steering wheel & various items have to be removed

    The official count is 343, but there was also a volunteer who lost his life
    aiding in the initial rescue efforts. And I will never forget them as
    long as I live,
    nor should any American.

    Sometimes it's best not to ask why, that part will drive you crazy. It
    may be because it's weak and in some areas and/or at some times there's
    more outside interference than at others. Or the temperature could
    affect it, or the way you park your car the magnetic field of the earth
    could affect it. Just accept that it happens, and be thankful that it
    has happened to many before you so that there's experience to help you
    out.

    Yeah it's weird... it usually fails in my garage or between -5 and 5
    degree celcius. at +20 or -20 it starts with fewer problems. (it
    still does it sometimes)
