Goodman 80plus unit goes through set up/draft inducer/ok new hot surf ignitr -glows relay clicks
And no flame ingitr clicks off and unit begins the start up again and yes there is a gas supply. Hope u can help me thanks.

Check for 24v to gas valve when the relay clicks to kick the gas valve on (this will be between the time the glow plug starts glowing and shuts down) If you receive 24v to gas valve, but no gas flows (using a monometer to see if gas is actually being delivered to the burners is the best bet here) then you most likely need a new gas valve. Definitely some testing needs to be done to know for sure what the problem is.
