DownStream Trace Problem

I have occured problem on downstream trace on desktop code. if we used below code to trace, then tool is working but some features were not selected. ArcFM tool working fine.

private void GetGraphicsDataSet(int X, int Y, string strTraceType, string strPhasesToTraceEnum, string strProtectiveDevices, DataTable dtBarriersTable, bool bDrawComplex)
{
IMxDocument pDoc = pApplication.Document as IMxDocument;
IMap pMap = pDoc.FocusMap;

if (pPoint != null)
{
ITopologicalOperator pTopo = pPoint as ITopologicalOperator;
IPolygon pPolygon = pTopo.Buffer(5) as IPolygon;

ISpatialFilter pSFilter = new SpatialFilterClass();
pSFilter.Geometry = pPolygon as IGeometry;
pSFilter.SpatialRel = esriSpatialRelEnum.esriSpatialRelIntersects;

IFeatureLayer pFLayer = null;
IFeature pFeature = null;

UID pUID = new UIDClass();
pUID.Value = "{40A9E885-5533-11d0-98BE-00805F7CED21}";
IEnumLayer pEnumLayer = pMap.get_Layers(pUID, true);
pFLayer = pEnumLayer.Next() as IFeatureLayer;

//while (pFLayer != null)
//{
// int i = pFLayer.FeatureClass.FeatureClassID;
// pFLayer = pEnumLayer.Next() as IFeatureLayer;
//}

IFeatureDataset pFeatureDataset = pFLayer.FeatureClass.FeatureDataset;
INetworkCollection pNetworkCollection = pFeatureDataset as INetworkCollection;
IGeometricNetwork pGeometricNetwork = pNetworkCollection.get_GeometricNetwork(0);

while (pFLayer != null)
{
if (pFLayer.FeatureClass.ShapeType == esriGeometryType.esriGeometryPolyline)
{
if (pFLayer.FeatureClass.FeatureCount(pSFilter) > 0)
{
IFeatureCursor pFCursor = pFLayer.Search(pSFilter, false);
pFeature = pFCursor.NextFeature();
break;
}
}
else if (pFLayer.FeatureClass.ShapeType == esriGeometryType.esriGeometryPoint)
{
int FeatureClassID = pFLayer.FeatureClass.FeatureClassID;
}
pFLayer = pEnumLayer.Next() as IFeatureLayer;
}

//Draw Complex Boolean
IMMNetworkAnalysisExtForFramework pNetworkAnalysisExt = new MMNetworkAnalysisExtForFrameworkClass();

}
