I was told by a mechanic that I will need to replace ABS pump. on 1990 Nissan Maxima

Is the ABS pump and the ABS
module unit both are the same? How much would cost to replace the ABS pump on Nissan Maxima 1990?

With the age of the vehicle you may real trouble locating these parts. The module is about $700 and the actuator is $1,000. Why do you need to replace them? Codes, pump continuously running, no ABS? Did you check the relays?
