When you try to start the car does it have a security light flashing? If not, you can use a scanner to see if the crankshaft sensor is picking up a signal, if not I would try replacing the crankshaft angle sensor. Here is a guide that can help, and I have included the crankshaft angle sensor location in the images below.

This guide shows how to use a scanner. You can get a CAN scanner (Controller Area Network) from Amazon.

Here is a video to show you how:
