Hi,

The most common cause of a no spark condition is a faulty crankshaft position sensor. If you have a live data scan tool, connect it and crank the engine. Do you receive an RPM signal? If you don't, suspect the sensor. Take a look through this link. It reviews common symptoms.

Start with this. Also, I attached the directions below specific to your vehicle for replacement. I hope this helps.

Let me know if you have other questions and what you find.

Take care,

Joe
