98 Plymouth 2.4 camshaft position sensor

[goatfan]

My voyager snapped a timing belt so I replaced the belt, head and cam position sensor. I tried to start with no joy, rechecked the belt settings everything looked good, still won't start. I disconnected pulled the cam sensor plug and it fired up. Is there a learning process for the sensor or do you think it is just a bad new sensor? Thanks for any help.
