If so the crank posición sensor is move And still don have spark can the problem be the computer or sonthing else

If it's a dohc then yes the sensor has to be set with a timing light. Even if it's not set correctly you should still be getting spark out of the coils just not at the proper timing. Have you checked your check engine codes? Use non digital multi meter to check them. Service manual will explain how and what they mean. Have you tested your pcm? If this goes bad you will not have spark. Have you checked your timing belt? If broke you will have no spark and possibly no compression due to bent valves.
