I have a 4144410a hwsv9500 furnace that comes on but no heat it sound like the pilot didn't come on I think it is a intermittent pilot cound someone help me .

Good luck with finding info on that unit. It is a Quatro by name and I believe the manufacturer is out of business.

Below is the only info I believe I have for the pilot of that unit. You might check to be sure the pilot orifice is not plugged up wit dirt or debris. That would stop the unit from working. NOTE if you do not know what you are doing call a pro for ON SITE service since I can be of no further assistance with this unit.
