I was sitting in car with the ignition switch in the on position,(motor not running) and I smelled something like wire burning and saw little wift of smoke under the glove box,I turned switch off and it stopped,but now the car will not start ,I took out the glove box and could not see where anything got hot,I replaced the circuit open relay and still nothing I sprayed starter fluid in the throttle body and won't fire,what should I do next.

Check all under hood and under dash fuses with a test light or multi-meter. Also, check for any fusible links.
