I bought a 98 t/a. The ABS is INOP, the Traction Control is INOP, the Brake light is on. Usually the warning lights just come on when i start the car, but occasionally thay will be off until i start driving about half of a block. Does anyone know what would cause this? I've been told that it could be my ABS sensor.

ding ding..you may have answered your question. a faulty sensor or open wire or bad connection will cause the system to be inop.
