So is the whirring sound like the engine is turning over easier than normal? How many miles on your Civic? Remove the oil fill cap. Then have someone try to start the engine while you look to see if the camshaft is spinning? With a flashlight you should see the camshaft spin through the oil fill hole while the engine is cranking over. If it isn't spinning the timing belt has broken. Please let me know what you find out.
