History? did this just happen, or did you just buy it like this? If it's been sitting, then the linkages are rusted up tight under the floorboard. Squirt the shaft that the pedals ride on with some soapy water if rusted, or penetrating oil if already greasy and then hold one pedal up while you push the other, then switch pedals. repeat until they pop right back up and don't stick. If they're loose already make sure none of the linkage fell out from a broken cotter pin.
