All new sensors,,,did you perhaps change the crank position sensor, it is sometimes nec. to do a crank re-learn after installing a new crank pos. sensor.

If it is the crank sensor,,it has to be re-learned by a dealership or a tuner with the software to communicate with the ECM..If you have the old crank sensor put it back in and see if the car starts up.
