York PT9 Furnace 3 Red Blinks
Woke up this morning to -14 without windshield and my York PT9 furnace is not lit. It is blinking 3 red lights which means faulty pressure switch, broken pressure switch hose, blocked vent pipe or faulty inducer. It's not lit. I tried blowing in the tube to he pressure switch and from the induce motor to pressure switch. Both times you hear a click and it resets to green. But as soon as thermostat calls for heat induce motor runs for a short bit but never lights and back to square one. I went out and as far as I can tell the intake and vent are not clogged.
Suggestions?

Same 3 blinks for my Luxaire (York) TM9X
The problem has been intermittent, it first started doing it on New Year's Eve. It would attempt to start up but then stop. I found that it would run fine for at least half a day, if I turned it off at the thermostat for several hours and then on again.
The HVAC guy who installed it, cleaned the flame rod sensor (I believe) with steel wool and it was working without any problems for about two weeks until last night.
Last night, the motor would start but no red glow or flame and then stop with 3 red blinks. I attempted to stop & start it again several times throughout the night and it finally started up again 7 hours later. It's been running ever since (4 hours now). HVAC guy says it may be related to extreme cold (-14, -35 with wind chill), back draft through exhaust, pressure switch or the igniter.
Any advice would be greatly appreciated. Thank you!
