Need help! Amana air command

Hi all and thanks in advance.

Amana air command HI efficiency 80 gas furnace, white rodgers model 50a50-206. I am getting the three flash code which indicates pressure switch stuck open. My inducer motor is not kicking on which is causing this. I have tested with my multi meter and it is not getting any power out of the circuit board. It has 120v going in and 0 out. Yes I made sure the natural switch was pressed and was continuing to get the three flashing lights while checking. I have 24v on the side of the panel from W to C and from R to C. I have checked directly off the board and neither where the red to the ignitor or the purple to the inducer fan have any power. Is there something I'm missing or did my White Roger's model 50a50-206 go bad? Again thank you!
