I had a abs fault on my early 1986 2.3 16v that I have just sorted, the abs light would go off on start up and come on when you move foward, with the car up in the air the rear wheels would not put the abs light on both front wheels would. I fitted spare sensors that had even though the reading was ok on them Tried a new ovp It ended up being the ecu that people said to me never go, I had a spare abs ecu from a abs2 system(87 onwards) with a plastic body from a 2.6 with a different part number and It solved the fault!
