There isn't a relay for the starting system. I suspect a faulty neutral switch, or clutch switch (depending on if automatic or stick shift) You can follow the path of current from the ignition switch to the starter using the wiring diagram. Click here for diagram. If you have further questions feel free to reply.
If there is power TO the neutral switch on the purple wire AND power thru the switch when trying to start it. the switch is good. Next step would be to check for battery voltage at the purple wire where it connects to the starter. If it has power there when trying to start it, the starter is at fault.
