replacement part # for a weather maker 8000 58wav

I have a goodman natural gas furnace no AC unit. I have been having an issue with it for a few weeks. The control board shows no code just solid red LED. When the furnace goes through startup cycle it runs the blower and induction motor heats the hot surface igniter clicks the gas solenoid, but no gas seams to come out and it does not ignite. I do not get a no flame code. There are also times when I go through the run sequence that the induction blower will run then stop 2-3 times the igniter will not come on and then it will stop all activity as though the pressure switch was not detecting the induction blower was on. I assume it is in lockout, but even when I cut power to it the lock out seems to continue as it will not try to run anything. I have tried cleaning the flame sensor, removing the filter, replacing the control board, replacing the flame roll out sensors. I am not sure what else I can do at this point especially given the furnace does not respond in the same way each startup attempt.
