: hey there guys again,, I m trying to get my j30 again . ABS light on
I don't think its working at all . no noise that I can hear at all from pump or relays . I got a used pump from ebay replaced it still the same . think my old one was good too. how do I test the ABS system for good to see if it is working ?

when I step on the brake suddenly it don't feel pressure or pulsating which led me to believe abs not working..
I also looked at wheel speed sensors and believe tested them a while back they were good .
replaced both relays. I
there is a 30amp link fuse and a 20amp fuse they appeared to be good
I ve done so much to this car t-belt , egr tubes cleaned , fuel injectors and much more , now I m determine to fix the abs .

what am I missing !!!
