    I just to possession of an 82 Mondial 8.
    About half of the time I hear the Fuel pump buzz and about half the time you turn the key and nothing. If I turn the key multiple times eventually I hear the fuel pump buzz. Any idea why this is happening?

    The fuel pump should not run until you crank the engine. It is activated by a switch in the fuel injection unit, attached to the air intake flap. If you remove the air cleaner, you will see a round flap that you can easily push down with your fingers. Turn on the key. The fuel pump should not run. Lightly push the flap. The fuel pump should start. If the fuel pump runs without pushing on the flap, there is a problem, most likely that the flap is dirty and not closing all the way.
