  The paper is concerned with the existence of positive weak solutions for a
new class of $\left( p,q\right) $-Laplacian elliptic systems in a bounded
domain by means of the method of sub-super solutions. Particularly, we do not
need any sign conditions for $\gamma \left( 0\right), g\left( 0\right), f\left(
0\right) $ and $h\left(0\right) $. Moreover, a multiplicity result is obtained
when $\gamma \left(0\right)=g\left( 0\right)=f\left( 0\right)=h\left(
0\right)=0.$ Finally, we give some examples to verify our main results.
