abs light stuck on

have no idea why 1995 monte z34 any ideas

have you checked the fluid level in the master cylinder??? I'm not sure if the ABS light would come on if the fluid were low, but it'd be a good start. Also, have you had any brake work done recently?? There may be something that needs to be reset.

fluid level is good vacume hoses are all connected no break work recently.

hmmmm....yeah.....ummm....try posting your question in the lumina forum....those guys are good.
