    92 = fuel injection..
    Black smoke = Running rich
    Start up but quit = problem when it warms up.
    I would try replacing the coolant temperature sensor. Make sure it is the one the engine computer uses, not the one for the temp gage, some vehicles have both.
    Just my guess.

    just a thought ...you might have dirt in the tank or in your carb /jets.....a clean fuel system is a happy fuel system!
