When a thermo coupling fails you can relight the pilot--but it will go out as soon as you let go of the button.
OP can't get the pilot to light at all---Often simply turning the valve to 'OFF'--then 'PILOT' and hold the button down for one minute--then hit the clicker ---will work---it's worth a try.
