If changing the camshaft position sensor doesn't turn on the car, will replacing the crankshaft position sensor do the trick?

Hello,

Yes it will. Your vehicle's Power-train Control Module (PCM) interprets the signal from the Crankshaft Position Sensor (CKP) to determine the speed of the crankshaft to aid in the firing of the spark plugs and for monitors such as misfire detection. If your vehicle's CKP signal is not getting to the PCM your vehicle will not start. I have included a few links down below for you to go to down below
