on mine if you hold down the button too the right it should be illuminated orange if locked out, press and hold this button then slack off the bleed nipple on top of the pump you should see some bubbles come out, tighten the bleeder, wait a couple of mins and repeat this process, until all the air is out of the system then eventualy the burner strikes up, steve
