Guys I need some opinions this am. Working on a Tempstar NUG5075BFA2. It has a VR8204M1075 gas valve. The t-stat calls for heat, inducer goes and closes the pressure switch. They the direct spark ignightor starts sparking and there is a poof of gas that comes from the piliot tube that imd goes out. The gas valve is getting 24v on the red wire and 12v on the black. Do you guys think the valv is bad? This is the first one wire spark ignition system I have seen.
