picture 1 is an inducer motor and pressure switch and vacuam line i was talking about,this is an 80% furnace but concept is same on 90 plus furnace just differant location.

in picture 1 on the top left side of burner cover the red wire closest to heat exchanger is the flame sensor wire

So do you think that was my problem, those two yellow wires? Should I clean the tips? or do you have another idea?

Ok so it's still happening...I double checked and it's actually an EIGHT flash error. If I look through the window I see that the ignitor never heats up when it fails to light and the gas doesn't come on. This leads me to believe that the issue is

1) lack of pressure build-up by the initial fan (is that the right term)
2) bad electronics which are sending bad signals

It still seems odd to me that a 30 minute power cycle resets it and then it works fine...any ideas?

I see your still having problems also. Mine is odd to me. When I took the door off it started working fine, when I had time later to put the door back on, it started doing it again.

I took the door off and it works. I know I can't leave it like this, but only time I think of working on it, is when it's too cold to have it off.

or the e-mail I got that reminded me.

Did you find the rubber hose from the pressure switch to the inducer draft motor? Did you blow through the hose towards the blower housing and see if you can clear it? or take a small stick pin and push it through the prong sticking out of the housing to see if there was a blockage?

Is this for me?
