ComfortMaker Honeywell SV9541 doesn't heat

I have a ComfortMaker furnace with a Honeywell SV9541 gas valve. My heat will not come on. When you set the thermostaht to call for heat, the fan kicks on, the ignitor lights the pilot but there is no gas flow for the burners to kick on. The light flashes 6 + 1. Does this sound like a gas valve problem or control board or pressure switch?

Inducer motor kicks on, ignitor lights the pilot, pilot burns for a few minutes then everything shuts off til next cycle. System locks itself out in soft mode. Resetting system produces same results. I can replace any of the parts myself. I would just like help narrowing down the problem so I don't buy any unneeded parts.
