I bought a 92 Accord EX 4dr A/T with 172k for $1500. The ABS light always comes on shortly after starting to drive. How do I disconnect it since a fix pump or sensor seems to be an expensive fix?

 

Did you pull a code for it yet? If it has a main code of 4 then try cleaning the sensors. I did this recently and had to spray them down a lot with wd40 then wipe off all the crud. If you have a pump over-run try to bleed your abs system.
