We establish the existence, uniqueness and the blow-up rate of the large positive solution of the quasi-linear elliptic problem $$-\triangle_{p}u=\lambda (x)u^{\theta -1}-b(x)h(u), in \Omega, $$ with boundary condition $u=+\infty $ on $\partial \Omega $, where $\Omega \subset R^N$ $(N\geq 2)$ is a smooth bounded domain, $1<p<\infty $, $\lambda (.)$ and $b(.)$ are positive weight functions and $h(u)\sim u^{q-1} $ as $u\rightarrow \infty $. Our results extend the previous work [Z. Xie, J. Diff. Equ., 247 (2009), 344-363] from case $p=2$, $\lambda $ is a constant and $\theta =2$ to case $1<p<\infty $, $\lambda $ is a function and $1<\theta
