I have 86 Mazda Rx-7. Every thing was working fine, until 3 days ago when I went to start the car and nothing happend. I know it's not the battery. Please help me.

How do I know if it's the starter, the coil ignition, or the switch (key switch)? Or even maybe it's something.
Thanks in advance

were going to need more info that that. Do your lights come on at all? if you do have lights do they dim when u try to start it? any info would help in determining whats wrong with your car
