So I busted out my service manual and EVTM today and started monkeying with the ABS system on my '90. Both ABS and Brake light on constantly, no power assist to the brakes, Pump not running.
So I start the troubleshooting and I get as far as the first test where you disconnect the pump power, start pulling on the harness to disconnect it so I can check the voltage to the pump.... then I hear this nice little noise start buzzing. The pump had kicked on. So I started wiggling the wires again to see if I could make the pump kick off, couldn't do it. So I topped it off with more fluid, pumped the pedal a few times to try to refill the system.
So aside from needing a new accumulator, my brakes work again by wiggling a wire. Arrrgh!
