    While driving to work, my wife noticed the oil light flashing on our 03
    Pilot with 64k . So, she stopped and checked the oil level and it was
    full -- a recent oil change. So, she tried a restart, but the engine would
    not turn over. The car was towed to the dealer.

    I could only think that -- given a full oil level -- the oil pump had failed
    or a sensor was bad. The problem -- a dead cell in a Honda battery which
    was only 23 months old. Covered under warranty.

    Could not start = won't crank? In hot climate batteries fail more that
    up here in North. Heat is worse for battery than cold.

    My guess:
    A dead cell would cause a voltage drop. Sufficient reduction would cause a
    corresponding voltage drop at the oil pressure sensor, which the ECM
    probably interpreted as a momentary low oil pressure.

    When your oil light flashes (as opposed to simply illuminating), this means
    the oil pressure dropped momentarily, then recovered.

    Your wife was extremely wise to immediately stop and check the oil level.
    Many people would't have been as diligent.

    In the old days, cars I had were equiped with ameters and oil pressure
    guages. You knew what you had.
