Then the only thing I can think of after doing thay is start swapping parts over, but that could get expensive.

thats exactly what i have done,well i tested all sensors and replaced 1 (£110 new

),replaced both cv joints as teeth were mega rusty,replaced abs pump and still no joy so ive just ordered a used but tested surge arrestor relay from ebay so in theory there isnt much more to try.
ive done a load of investigation on the internet about my abs system and its fault and learned that my car being a 1990 model uses a difernt system to every cavalier/calibre from 1992 onwards but on a plus side many of the abs componants on mine were used on carltons,senators and monzas.apparently many carltons suffered abs problems using the system thats on my car and the common faults were the abs sensors and the surge arrestor relay,its just a shame its a rare sight to see a carlton,monza or senator in a scrap yard these days,il post up what happens when i fit my new relay when it turns up next week,fingers crossed it will fix it.
