dumb question, but did you check your fuses / etc? If you shut it off and now it won't get spark, then something happened between when you turned off the key and when you went to restart. Start simple with the fuses / relays and go from there.

Where did you get your new cps from? If it was anything other then an oem one that may still be your problem. After market are known to be bad right out of the box.
