In this paper we consider the quasilinear system \[ \left\{\begin{array}{ll} -\Delta_{p}u=\lambda g(x)f_{1}(u,v)+\mu h_{1}(u) ~~~~ in~~ x\in\Omega \\\\ -\Delta_{q}v=\lambda g(x)f_{2}(u,v)+\mu h_{2}(v) ~~~~ in~~ x\in \Omega \\\\ u(x)=v(x)=0 ~~~~ on ~~ x\in\partial\Omega~~. \end{array}\right. \] \\ where, $\Omega$ is a bounded domain in $\mathbb{R}^n$ with smooth boundary $\partial\Omega,$ $\lambda>0$ is a parameter. Here $g$ is $C^1$ sign-changing function that may be negative near the boundary and $h_{1},h_{2},f_{1},f_{2}$ are nondecreasing and satisfy in additional conditions that we shall express the follow. Also we introduce the energy functional associate our problem then by energy functional we will discuss in context existence of solution for said problem. \end{abstract}
