What is the part I need to replace the spark modulator?
Answer P, your model should read JGP336BEV2BB (BB instead of 88). The spark module is part number WB13K25. Thanks!
on the 2 stove top burners, 2 diagonal burners do not spark or light up.
I purchased 2 ceramic ignitors (WBK13K29914) and replaced them and it still does not spark or light up.
It it the spark modulator?
Answer Steve, You're going in the right direction, when you turn on any valve all the igniters should spark. You'll need to check the wires to the two igniters that don't spark, make sure they're not broken or shorted to the chassis and replace the spark module WB13T10046 if alls OK.
