Hi and thanks for using 2CarPros.com.

No spark can be caused by a few things. First, I would check to see if there are trouble codes stored in the computer. Here is a video which includes a general directions for using a scanner:

If there are no codes and you have access to a scanner which can provide live data, check to see if there is a crank sensor signal. If you find the crank sensor is the issue, I have attached directions for removing and replacing it.

I have a feeling the sensor is the issue. Do these things and let me know what you find.
