Is the security light flashing when you try to crank it over? Also it could be the auto shut down relay. I added a diagram below for that. Next I would disconnect all injectors and O2 sensor to see if the spark comes back, you could have a short in something causing the spark not to be generated.
The relay is in the power distribution center under the hood.
Please let us know happens so it will help others.
