the car turns over but does not start, no spark to the spark plugs

Diagnostic fault codes never say to replace parts or that one is bad. They only indicate the circuit or system that needs further diagnosis. A defective sensor is only responsible for the fault code about half of the time. First you have to check for wiring / connector problems and mechanical problems related to that sensor.

With the ignition switch turned on, check for 5.0 or 8.0 volts on one wire for the crankshaft position sensor. To be accurate, you need to back-probe through the back of the connector body so the readings can be taken with the sensor plugged in. Another wire must have 0.2 volts. If either of those wires don't have the right voltage, I will dig up a wiring diagram to see where to go next.

The third wire is the signal wire. You might find 5.0 volts or 0.0 volts, but that does not tell us anything. You need a scanner to view live data. That will tell you if the Engine Computer is receiving a signal during cranking.
