What is the Model number of the boiler and does it have an integrated boiler control? If so what is the make and model. Then I will be able to answer your question. If it does have a boiler control are any lights flashing?

Will the valve open if you give it direct 24 volts? Test this with gas shut off and listen for the audible click of the solenoid in the valve. Do a step by step test of the nine pin connector, if that is difficult for you to follow I can send you by e-mail the procedure. My e-mail address is gastc@cox.net.

Also, there is usually a tag on the ignitor that has the ignitor model number. Once you know that, you can find out what the resistance should be at room temperature or post the number here.
