It depends where the exhaust seperated. The engine needs back pressure which is provided by the catalitic converter in order to run right. This may cause it also not to start. Or maybe it seperated befroe an O2 sensor and is not getting the correct readings. Its also possible that the fuel pump failed do to no gasoline. The gas lubricates the fuel pump.
