I have an amana m#guic090da50 s#9809130557 the inducer motor stays on and the trouble codes flashes two for pressure switch closed. But if I remove the suction hose frm switch to inducer motor then out it back the board clicks twice then the furnace lights up and operation is normal for one heating cycle. But the inducer motor stays on even after the heat cycle is done and even on cooling mode also when the system is switched to off on the thermostat. What can I check to try and fix the problem. I also noticed that the white wire from motor is connected to the power whip and the black runs to the board. Should it be connected to straight power or should both wires be connected to the board.

Sounds like you have a stuck induced draft relay. If the relay is on the control board, you will need a complete new control board.
