Check for 12V DC at gas solenoids while spark electrode is firing.
Red wire from ECO to solenoid then to black wire (Grd)
Also check that all grounds are clean/tight
Main gas orifice is not plugged
Spark electrode gap is 1/8" and no cracks in ceramic insulator (unplug red wire on ECO to gas valve. Stick a fiber washer (some type of insulating material) between electrode and ground rod....fire unit. If you see a spark jumping from the ceramic to the ground rod or bracket, replace the spark probe
