Just been out for another ponder over the engine bay. Some things are starting to make a bit of sense to me now. Before I bought the car, it had been used as a track car. Now I have been reading about the abs system on bluecossie and apparently pre june 1989 cars were supposed to have an orange relay in the fuse box in relay number VII ?? just checked and mines missing. mines a nov 1988 car. If its been used as a track car, im assuming this could be my problem and that a previous owners has somehow disabled the abs system.

does this sound feasible and would the missing relay cause my symptoms??
