You should be able to get gas to come out of the pilot tube by depressing the valve and setting to the pilot position. All safeties would be in the circuit to prevent the main valve from opening but not the pilot.
You are not charged any extra no matter how long we work on the question.It will stay open until you leave a rating or we decide we can not help.Lets unscrew that tube and hold the knob in position that gas should come out. Make sure power is off and of course do not keep holding down for a long period if gas comes out as we do not want to blow anything up. This is just to see if the valve will send gas out. .You can come back to question anytime and we will continue.
