Is the fan switch on your thermostat in the "on" or "auto" position

Open up your biggest furnace door only so you can see what is happening in the operation sequence. Need to know if exhaust gas motor fan (inducer) starts off the sequence, and then if in a number of seconds you get a bright yellow-orange glow or pilot to come on, at least. And then if you get any burner fire to occur for at least a few seconds after that.
