1999 Chrysler Concorde ABS BRAKES

REPLACED BRAKE ALL BRAKE LINES ON CAR, THERE
ARE 2 LINES FROM MASTER CYLINDER TO ABS PUMP, 2 LINES FROM ABS PUMP TO FT WHEELS, 2 LINES FROM ABS PUMP TO REAR WHEELS. MASTER CYLINDER BLEEDS GOOD, CAN BLEED RIGHT REAR WHEEL, BUT CANT BLEED THE OTHERS. BRAKE FLUID WONT GO PAST ABS PUMP. THERE ARE NO OTHER ITEMS EXCEPT ABS PUMP BETWEEN MASTER CYLINDER & WHEELS. WHAT DO I NEED TO DO TO BLEED THIS SYSTEM PROPERLY.
