My inducer fan starts and the igniter starts to glow. The blower does not come on. It will not ignite. I hear a click like the gas wants to come on then the igniter goes out.

Try cleaning the flame sensor with steel wool or sand paper.

It also sounds like it is not sensing the inducer fan. Check your connections from inducer fan to gas valve.

Make sure the knob on the gas valve is set to "on" & the manual valve in the gas piping external to the furnace is turned on.
