IF the furnace was running from the flood, that means the control board got wet and started the fan relay circuit. You need to remove the circuit board and completely check it for corrosion. There are 2 common things that prevent cycle after initial run.
1. Stuck hi limit switch(Most common)
2. BAD logic in Circuit board. Replace the board. IF the Board got wet, It needs replaced. Doug
