My 96 Nissan 200SX SE-r won't start

Hi,
I seem to have the excat same problem. There is a noise when I turn the contact on, as if the fuel pump was building pressure. I think the fuel line is OK.
I wonder whether I'll have the change the coil. But I can't find a decent video showing how to do it. And I am not even sure this is the problem.
I know this is a little too vague. But I am interested in the answer you'll provide to the first person. It might give me ideas.

Thanks in advance,
rafiki

PS: mine is manual, and is actually a 200SX base, year 1996, but I think it will be similar.

I guess it is because it is too vague. That's why my problem seems the same.
- I hear "click click click." When I turn the key;
- I have energy from the battery, for sure (I even charge it, in case it was too weak);
- I checked the spark plugs, they are in a good shape and have been firing recently;

so I guess my question would be
- what is the most likely problem between coil and starter engine, and whether or not it is different parts on this car (I just got it, and I haven't had time to find a Chilton or Haynes book yet, as the autoparts store nearby doesnt have any for this type of car)
- and if it is the coil, do you think I can change it myself, or will I need the help of a trained mechanic with special tools (same question for the starter)

thanks,
and I hope this helps the first person as well,
