When I say "jumping wires" I mean twist them together. But, it you hear your igniter clicking, then I think that means it is calling for heat. Make sure you can see the igniter making sparks.
I think you need to verify you have gas to you heater/waterheater. If it were me, I would make sure the water heater is full of water, and try to light it. Once you know its on, you know you have gas at least to there. I installed a new gas line for a heater in my garage. I had to turn the gas off at the meter. Once the gas is turned off, it takes a while to get back to the appliances.
We have to winterize an old house in southern utah every year. We just get 3-4 gallons of RV antifreeze.
1. Turn off water into the house
2. Open all taps
3. Drain Hot Water Heater
3. Dip all water out of toilets
4. Put the RV antifreeze in every sink, toilet, tub, etc.
When you turn it back on, make sure all the taps are turned back off.
Was this house really winterized, or was the water just turned off?
One more thing. I think you can get Questar to come and check your water heater/furnace for free. (I know they used to, but I'm not sure now)
A heating guy will probably charge you $75.00
