The effect of disorder on interacting fermions of both spinless and spinful two coupled chains has been examined by applying the renormalization group method to the bosonized Hamiltonian. A phase diagram is calculated as a function of disorder, interaction and interchain hopping to find localization induced by impurities and confinement of single particle.
