The IGNITION MODULE is under the coil pack, the thing that ALL the plug wires go to.
Both module and coil pack needs to be replaced at the same time! This is most likely your trouble.

I would check the resistance on the coils first if they are ok then I would check the power going to the module if there is no power then I would check for broken wire or a bad pcm
