Question about Water Heaters
One side of Piezo wireing goes to Igniter but i don't know where the other lead goes.
Piezo igniter only needs 1 wire to cause spark.
The other wire might connect to electronic gas control to report error, but brand type and age of product is not described in question.

Try removing the safety cut out (looks like a resistor in a plastic sleeve going to thermostat terminal) . Just disconnect it at both ends and connect the female spade from power wire directly to thermostat male terminal where the cut out was connected and try it. If it works, replace it when you get a chance. That protects system in case of flame jumping up in that area due to problems or spider webs etc. Once it's been tripped, it's no good. If that's not the problem, try cleaning your ends of your electrode, and make sure they are in front of flame when burner ignites, as it also act as a flame sensor. Let me know how you make out.

are you getting spark out of it? when you click it can you see a small electric spark? if you see it spark, then the thermocouple will probably need replacing
