ABS problem

I have a 1990 limited with abs. The problem is there is no power assistance when stepping on the brake pedal and the pump under the coolant tank runs continously when the key is on. The red brake light is always on, but the amber check anti lock light does not flash or come on at all. I think that it may be the pump not functioning properly. This system is new to me so any help on this would be greatly appreciated.

i believe the pump is lifetime warranty, however sometimes the accumulator goes bad an wont let the system get up to pressure and makes the pump run continuosly. you need the gauge the dealer has to properly diagnose this condition.
