Ok with the crank sensor only registering 2.5 volts and the sensor is new this is either a timing problem or a communication problem from the ECU to the sensor. However with the sound you are hearing this is more likely a timing issue. The next step would need to be having the timing checked because this will affect the crank sensor.
