or it could be your ignition wire coming from your ignition switch. Sometimes there is a break in the wire. It's a black/yellow striped wire coming from your ignition switch to your starter. If your car does not start try jumping from your battery to the starter. not the hot wire but there is a small wire that tells the starter to kick over it's black/yellow striped also. That could be your problem. Just jump another wire from your ignition switch out to your starter and that should fix the problem, but beware you will not have to have the clutch engaged to start your car. I have had 2 cars do this to me, a 91 hatch and a 91 Integra.
Hope this helps
