Hi, my name is Mike and I have been in the home improvement and repair field for 20 years. I will be glad to help you today. Both codes indicate a fuel delivery issue. The first thing I would check is that there is not a restriction in the gas inlet. There should be a screen there where the gas line connects. Also check that all connectors are pushed into PCB and be sure that the gas valve is turned on. Check voltage on the gas valve. It should be 24 VAC. Hopefully it is not a faulty gas valve but that is also a real possibility.
I haven't heard from you. Was the information I provided helpful?
