Yep, it won't start with the P0315 Code, "Crankshaft Position System Variation Not Learned" so it must be reset when you replace the crankshaft sensor. Here are the instructions on how to do so:
Note The Crankshaft Position Variation Learn procedure is also required when the following service procedures have been performed, regardless of whether DTC P0315 is set
An engine replacement
An engine control module (ECM) replacement
A crankshaft balancer replacement
A crankshaft replacement
A crankshaft position sensor replacement
Any engine repairs which disturb the crankshaft-to-crankshaft position sensor relationship.
Note: The ECM monitors certain component signals to determine if all the conditions are met to continue with the Crankshaft Position Variation Learn procedure. Ignition ON, observe the DTC information with a scan tool. Verify no other DTCs are set, except P0300 or P0304, or P0315
If DTCs are set, except DTCs P0300 or P0304, or P0315, refer to Diagnostic Trouble Code (DTC) List - Vehicle for further diagnosis.
Select the Crankshaft Position Variation Learn Procedure with a scan tool and perform the following:
Note: Close the hood.
Note: The engine must be at operating temperature.
Block drive wheels.
Set parking brake.
DO NOT apply brake pedal.
Turn the air conditioning (A/C) OFF.
When directed, apply and hold brake pedal for the duration of the procedure.
Ignition ON, engine running at operating temperature.
The vehicle must remain in Park or Neutral.
Note: While the learn procedure is in progress, release the throttle immediately when the engine starts to decelerate. The engine control is returned to the operator and the engine responds to throttle position after the learn procedure is complete.
Accelerate to wide open throttle (WOT) and release when the fuel cut-off occurs. The scan tool displays: Learn Status-Learned this Ignition.
Verify DTC P0315 ran and passed this ignition cycle.
Once the Crankshaft Position Variation Learn procedure has successfully completed, and in order to store the crankshaft position variation values in the ECM, turn OFF the ignition and verify all vehicle systems are off. This can take up to 2 minutes.
Please let us know what happens.
