there was never a gasket in between the differential and the housing. rtv gray or black silicone is a very good sealant for that.

Ok thanks guys. On the electric side.. all fuses are good but my fuel pump circuit is gone too. So I bypassed that. But I was thinking maybe they both ground somewhere or theirs one reason why two electrical circuits are dead in my car. ?

Do you know how to use a multi-meter? The fuel pump wiring is pretty simple and easy to trace. With the FSM in hand, the dash wiring becomes very easy to troubleshoot.
