Hi,
The most common cause of no ignition spark is a faulty crankshaft position sensor. I'm not certain what vehicle you have, so I can't provide the specifics for you. However, take a look through these links. They explain how a crankshaft position sensor works and common symptoms.

If you determine the sensor is bad, here is a link that explains in general how one is replaced:

I attached a pic below showing the location of the sensor on a Ford Taurus 3.0L as a reference for you.
I hope this helps. Let me know if you have other questions.
Take care,
Joe
