eh to me i dont think its the starter its possible, however a bad starter normally will click very loudly, and then when you hit it with a mallot or hammer it will turn over.
if its not clicking or trying to turn over, i doubt your starter is bad, has to be something else, ive replace MANY starters and never had then just not work, they either clicked when trying to start or they would get stuck and need a hit or 2 to start the car.
at most i would pull the starter and test it out and see if it works, but i dont think thats the problem, it could be though.
just dont want you going out and buying parts that might not work. or fix the problem at hand
