Teledyne Laars Series 2 Pool Heater won't lite

[pfeliciano]

I have a Teledyne Laars Series 2 ESC 325K heater. the heater won't lite. i have gas going to the front of the gas valve but nothing after the valve. I replaced the valve with a new unit but it still doesn't lite. I can not smell gas when trying to light. I do have spark. Gas tank level shows 40%. all worked fine last month. please help.

Check your ignitor generator. When you light your pilot light it sends out a electrical charge. Check you your pool heater manual or go on line.
