My 850 will not start 850 1993

Two weeks ago, my '93 850 would not start--plenty of gas and the battery was fine. I had the car towed to the local Volvo/Saab repair shop, after the car sat in their lot for 5 days, they said it was probably flooded, but I would need a new distributor and wires...$250 and two weeks later the car did the same thing, it started for a second and then died. It will not turn over it sounds like a whirring noise and it will not fire up. I am taking the car back to the same repair guy but wanted to see what anyone thought. Last time I posted a message up here, you guys were dead on. Thanks, Mark

    with an 93, you're getting into the age where all the sensors and relays go. In the last year, I've had to change my fuel pump relay, engine temp sensor, cam position sensor and I think the shop changed my throttle position sensor, because they couldn't find a problem with warm starting. At any rate,if you are getting gas it is not the fuel pump relay. sounds like the cam position sensor as you are getting gas in the cylinders but the engine does not know when to fire. This should show up on the diagnostic computer.

    There is a problem that causes flooding that is known as
    the "Lawn Mower Syndrome". Occurs after you start the car for
    only a few seconds as though backing out of the garage to
    get the lawn mower out. The car then cranks very quickly
    (the fuel in the engine is preventing the pistons from sealing
    so it easily cranks) and quickly floods. If it does start, it
    might stumble and then die. If this happens you often need to
    change the plugs and the oil (the oil will be fuel contaminated).
    Letting the car "dry out" for a while (read hours) and then it
    starts. Happened to us twice on our 95 855.

    Any chance the car was started for just a few seconds before you
    have the problem?

    This is just one possibility but it is somewhat common and would
    be seen only if you started the car for a few seconds. There are
    other problems like leaky fuel injector, bad pickup sensor for engine
    cam position, etc. that could cause this, too.
