Hi and thanks for using 2carpros.com
Cranking and not starting can be caused by several things. However, the idea that it is not showing any trouble codes leads me to believe it could be related to the crankshaft position sensor. The sensor is based on engine speed. Therefore, if the engine isn't running, it may not set a trouble code. Take a look through this link:
Here is a link that shows in general how one is replaced.
The technician you mentioned is basically right. Without the symptom, it becomes a guessing game. However, as I said, this is my first suspect. Here is another link that discusses crank but no start conditions.
If you suspect the crankshaft position sensor is the problem, here are the specific directions for replacement.
1. Turn the ignition switch OFF and disconnect the battery negative (-) cable.
2. Remove the air cleaner assembly .
3. Disconnect the crankshaft position sensor connector (A).
4. Remove the installation bolt (B), and then vertically remove the sensor from the transaxle housing.

- Install the component with the specified torques.
- Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.
- Apply the engine oil to the O-ring.
- Insert the sensor in the installation hole and be careful not to damage when installation.
1. Installation is reverse of removal.

Picture 2 shows its location.
Let me know if this helps. Also, if you have other questions, feel free to ask.
