Hello, its an electronic ignition furnace, no pilot light.

Tell me if you had a lot of sheet rock work done or not, that dust can block the AC coil and then when the furnace starts it will go off on its high temperature safety cut out.

If you can attach a clear well focused photo of the wiring diagram, glued to the inside of the blower access panel I can mark it up with trouble shooting directions, Use the paper clip icon at the right end of the tool bar above for that.

It is possible that door switch on the blower service door is also not closed properly, look at that also.

We can go from there.
