Any assiatnce would be greatfull

1. I short the TEST to common, the LED flashes (some code) and then the Inducer motor starts about 20 seconds later, then the Ignitor glows orange, there's no clicking sound for the gas valve to allow gas flow, then the ignitor goes out, and the blower turns on and goes through two stages. Then the LED is solid no fault code. I disconnected all leads on the terminal board to rule out a short.

2 I replaced the gas valve... not it.

3 I checked the pressure switch, when I suck in it it toggles, however when I check for voltage (24 VAC) there is none.
I jumpered the switch and same symptoms.

4. the inducer motor starts but squeels, I have 115 VAC to the windings.

5. I've cleaned the intake to the draft.

6. Is the computer control board FUBAR? Any way to check it?

7. MAybe the draft inducer motor not have enough back pressure to pressure switch? But what prevents the GSV to not cycle the solenoid? BAck to the comnputer?

8. Again no FAULT CODE this is diffciult to diagnose, your thoughts?

Thanks
