Boiler not firing up

My Weil-McLAIN boiler will not fire up. Replaced the thermocouple, aquastat and gas valve to no avail. Any suggestions on what to target next would be greatly appreciated. Chillin in Colorado...

Start with the thermostat. Jump it & see if the boiler fires.

Using a voltmeter, make sure you have 120 vac and 24 vac at the furnace control box. There should be a electrical diagram attached somewhere on the furnace sheet metal to show which terminals to measure. Troubleshoot from there.Good luck.

Come to find out I purchased a bad thermocouple. Bought a new one and it fired up. OMG, spent a few hundred dollars on parts not need due to a bad $10 part. Oh well, I have heat. Thank you for the replies and support...
