Could a faulty spark plug cause the distributor not to function properly? on 2002 Nissan Xterra

How hard is it to replace a distributor on a 2002 Nissan Xterra?

Is the problem NO spark? Have you checked?? Answer is no, on the spark plug! Not a problem for a 'mechanic' to replace the distributor but it is not for a job for the avg. DIY'er....
