    Ignite in what sense - chemical or nuclear fusion? In either case the answer is no.
    Chemical - the gas giants are mainly H and He. To ignite you need O, which you don't have in any significant amount.
    Fusion - this requires a very high temperature, caused by gravitational compression. You need to add a lot of mass to get there.

    If you mean is it possible to initiate fusion at the core a a gas giant, turning it into a small star, then no. The gas giants in our solar system just aren't massive enough to maintain a fusion reaction at at their core.
