    You can leave the top door off,just to see if it's going to light. Do you hear water slushing in the inducer?

    No water. But when I remove small grey tube from gas regulator, plug with my finger, the light turns solid red for about 6 seconds, then goes back to flashing twice.

    Shut furnace off,remove tube from inducer only,power furnace and suck on the tube like a straw,you will hear a click keep sucking keeping a vacum on the tube until you see an ignitor glow.

    Your furnace should have a plastic exaust pipe,does it vent through the roof or the side of the house?

    Most likely something is blocking the intake or exaust. It could be a chunk of ice or even a bird or wasp nest. When either pipe is restricted the pressure switch will not close.

    K, check and make sure snow or ice is not covering the intake and exaust on the roof, I'm willing to bet you have a ball of ice over the intake.
