I recently connected a gas range that has been sitting for a few years. (was used three years before it was disconnected) Since installing the range I've discovered that the gas is not flowing through it and it can not be lit. Could the line just be clogged and is there any way for me to unclog it?

Re: Gas won't flow through range
Might be a clogged line, could be your diaphragm in the regulator that is bad, you will need to disconnect the regulator where you hook up your gas line to the range then from the burners blow compressed air through them, I would suggest replacing the regulator, should cure the problem.

You either have an issue with gas flow from the control valves or with the piezoelectric gas igniters. Turn the knob to low and try lighting the burners by hand. If they work, then your problem is not gas flow but the ignition. Turn the knobs to light and see if each burner clicks and you see sparks at the igniters. If you are not seeing a spark, try cleaning up the igniter tips. If that doesn't do it, it is probably time to call the service technician (or the Hotpoint Customer Service hotline).
From what you've described and what I understand; the only part that requlates the gas flow "low or intermitten gas flow/pressure" is the "gas pressure regulator" located where the incoming gas flex-line connects directly.
The pressure regulator is about 3" x 3" metal square blockish' type device and can be replaced fairly easy. However, if and when replacing the pressure regulator, ensure you are using the proper gas - yellow teflyon tape of pipe dope paste to thread in the new part.
What is the model number of the range? (free standing - gas pilot only)
(The above suggestion is assuming you have the proper gas supply pressure to your home/range)
My next step would be to replace the two gas coils. They are located on top the gas valve. Disconnect the elect. leads, pull upward on coils. Replace w/newones. The difference is a primary and secondary, one has two elect. prongs and one has three. Note which one goes where when you remove them and install new ones in the opposite. These tell the gas valves when to activate and allow gas to flow to your igniter. When they malfunction, and they do, you wont have gas flowing.
