What year Sunline do you have and do you have a make/model number on the furnace?
It sounds like you have one of the older gas pilot versions. They had a few versions before the all electric ignition ones come to be. Some of the older ones were total all gas mechanical some combo gas pilot and electric. I may be able to help point you to some places to look, but need the model and year to help know which one you have.
Pics of the gas valve area help too.
Hope this helps
