Cam sensor has nothing to do with spark. It is there to synchronize the injectors properly. If it goes south, the usual symptom is hard starts, bucking, and sever misfires.
If, OTOH, the CRANK sensor goes, you loose spark. You also will only have the fuel pump running during the initial 1-2 second priming cycle. The pump will not be turned on while cranking other than this since the PCM is not gtting the PIP signal.
Your description mostly matches a crank, not a cam sensor failure.
