I would check your wiring for your CPS first...make sure your connection is good. Does it sound like it has good compression?
3 things required to make a vehicle run: Fuel, Fire, and Air
Fuel - check and make sure your fuel pump is running when the key is on; make sure you have fuel pressure at the engine (I think all vehicles have a little schrader valve on the fuel rail to check that)
Fire - check and make sure your CPS is connected good; may have gotten a bad part...it happens.
Air - shouldn't be an issue in this case
Something else you can try... unplug your battery overnight; plug it back in and try to start it. If it starts...hopefully your problem is gone. If it doesn't start...see what codes have returned and hopefully that will help you pinpoint your problem.
