Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now. Please give me time to respond as typing, researching and adding links takes me time to do so please be patient and often I will ask you questions to narrow down the issue to get is diagnosed correctly.
Do you have the front cover switch taped down and if so check and make sure that switch is good as that will cause the unit not to send power to the main gas valve. Let me know what you find.
OK is there two GRAY wires to that switch?
OK what color wires are going to the gas valve and can you check if the valve is getting power 24 volts?
Ok that gray wire should go to a switch follow it and that may be the issue.
Yes the pressure switch correct....that has to close in order for the gas valve to operate. That may be the issue here.

You can or jumper the two gray wires to the pressure switch together to bypass it and try it to see if the pressure switch is the issue.
