The pedal is stiff because you have no vacuum. You won't have any vacuum until the engine starts. That doesn't mean you have a leak - still possible but low on my list - as, without the engine running, a press or two on the pedal will bleed off any stored vacuum.

The pedal doesn't have to move very far (less than an inch) to change the state of the switch. The switch could be the problem but, as with a vacuum leak, it's low on my list.

Get an OBD tool and see if any DTCs are present. Modern cars are pretty good diagnosticians.

Edit: Try shaking the shifter while starting the engine. There is a Park/Neutral switch that can keep the engine from starting.
