If after connecting the plug to a good ground, you still have no spark, test the coils as listed here in techinfo.
This is a post from a different thread where Technical Ted explains how to test for power going to the ICM (ignition control module). That is the thing that the coils attach to, and will have a connector on the front of it.

James - Vats stands for Vehicle Anti-Theft System. If the ignition switch can't read the proper resistance of the key pellet the car won't start.
Here'* how to check for power going to the ICM.
Unplug the connector at the ICM.
Connect voltmeter or test light between ground and the P terminal of the wiring connector. The schematic shows the P terminal as a pink/blk wire at one end of the connector. The key needs to be in the run position.
If you have power then it sounds like the problem is either the ICM or Crank sensor.
No power will mean Vats, fuse or maybe even the ignition switch is bad.
If you wish to read that thread, it is here.
It has some good troubleshooting tips.
