well i finally got around to changing the accumulator today, and now instead of the pump running every pedal push and the yellow abs light blinking, the pump runs now every other pedal push and the light does not come on now. what the hell could it be now? any help is greatly appreciated.

The pump should come on every 2-3 light taps on the brake pedal. That indicates normal operation.

Did you bleed the brake system properly as outlined in Chris A.'s write-up or in a service manual? If not, you need to do so. I went from a dead accumulator that cycled the motor with every press(that's when I parked the car) to a new accumulator that gives me a good 4 presses before the pump cycles.

Just wondering, is it usually the accumulator, not the whole unit that is bad?
