Have you checked the rollout thermostats around the burner area. One of them could be tripped open causing this issue. Some have a reset button on them and others do not. They all have to be closed in order for it to work properly. Start there and let me know what you find.
They would look like this

Yes press on the button in the middle and see if one clicks, then try it. Let me know
Those two right in the front with the blue reset buttons.
Ok does the exhaust blower come on and run?
OK have you tested for power at the ignitor leads?
Also are you getting any error codes on the board?
Yes the leads to the ignitor check them for power. You should have a flashing error message on the board leds.
Set it to AC VOLTS 200 range and put it across the two leads to the ignitor and start it up ...after the inducer comes on what does it read?
YEs put your meter leads across the two to the ignitor and start it up see what you get on the meter
Ok well that is like half power so you may have a board relay issue it sounds like it. Do you get nothing then it goes to 65 ?
OK if nothing is flashing on the board at all and you only have 65 volts to the ignitor I would say the board is bad. Can you remove the board and check the backside for any burn marks?
The joint on the relay for the ignitor may be bad, the relay for the ignitor is on the board though
I would check the backside of the board where the relay for the ignitor is, see if one of the solder joints is bad. Or replace the board on the unit.
Not if the ignitor never glows
It could, you should then check for power right off the board to the ignitor to see if you have 120 if so then maybe a wire issue.
A couple joints look overheated....but nothing else. Can you check power off the board to the ignitor to confirm you are not receiving correct voltage?
Do you see the ignitor wires that go to the board?
I think there is an issue with that board for sure, nothing else really would cause that issue.
Does the inducer fan come on and run?
