Make sure the wiring and connections are all o.k. at and leading to the crank sensor.If any issues are found they will need repaired to correct this fault here.The code P1626 indicates the PCM (engine and transmission computer) has detected a loss of state of health from the theft deterrent control module.In almost all cases this is the theft deterrent control module at fault causing this issue here.This module is located under the radio on your model here as shown below.
If the crank sensor code comes back you want to check and make sure no terminals are bent in the connector for the crank sensor as well as all wiring is o.k. at and leading from the sensor.

The crank sensor fault will cause the engine to stall out but not the theft module.The theft module can cause a no start issue.I suspect it is the crank sensor fault here causing the stall out and can be the connection or wiring since the sensor was already replaced.If the connection and wiring are all found o.k. then usually this can be the engine computer needing replaced.
