Help No Spark

Okay So I have a 97 TJ with the 2.5 in it, I went to go over to my moms house when the jeep lost power so i towed it back to the house and hooked up an actron reader and gave me P0340 code so i replaced the CPS and still no power and then i replaced the distributer cap, rotor, the sensor that sits under the rotor in the distributer, coil, and wires and still can not get the jeeep to run. has anyone else have this happen to them?

You're absolutely certain there's no spark and that it's not a fuel problem? I only ask because you've replaced nearly the entire ignition system and not everyone knows how to verify whether there is spark or not and often just guess.
