    Colpitts oscillator - Wikipedia, the free encyclopedia

    There's no current flowing in your circuit and thus no oscillation.

    It's said in the words below the formula
    where the series combination of C1 and C2 creates the effective capacitance of the LC tank
    You also need to understand total capacitance of series connected capacitors and resonance frequency of a LC circuit LC circuit - Wikipedia, the free encyclopedia
