It sounds like there may be an issue with the ignition system specifically for the wok burner. Here are a few potential causes:
Faulty Ignition Head: The ignition head may not be generating enough spark to ignite the gas. Since you mentioned that a weak spark can be seen when foil is placed between the ignition head and earth, this could indicate a weak spark from the ignition head.
Dirty Ignition Head: If the ignition head is dirty or covered in grime, it may not be able to generate a strong spark. You can try cleaning the ignition head with a soft brush or a toothbrush to remove any debris or buildup.
Loose Connections: Check to make sure all the electrical connections for the ignition system are tight and secure. A loose connection could cause the ignition to fail.
Faulty Spark Module: The spark module provides power to the ignition system. If it's faulty, the ignition may not work properly. However, since the other burners are working fine, it's less likely that the spark module is the issue.
If none of these solutions work, it may be best to call a professional to diagnose and repair the issue.

I had a similar problem and discovered that the control knob had fried itself, most likely due to liquid penetration down the shaft of the control knob and into the control knob electronics. Inside is a printed circuit board with resistor, diode and a rheostat.The surface of the board was charred beyond repair. To trouble shoot the problem, open the cook top and hook the burner in question to one of the known good control knobs.If it ignites, then it is the control knob electronics.If it doesn’t, then there is something wrong with the igniter. Note: The 2-zone Wok Burner had a different control knob that the other burners. To open the cook top, do NOT loosen any of the Phillips screws on the sides.Here are the instructions from the user manual: Disassembly Shut off gas supply, disconnect the manifold pipe, disconnect the electrical power. Remove pan supports, burner heads and burner rings. Remove control knobs. In the event that the hob is built in, undo the bracket clamps underneath the work surface. Lift the hob on to the work surface. Unscrew the venturis on the high-speed and super high-speed burners using a 20 mm wrench. Lift and remove the burner rings and burner base plates. Disconnect the wires from the ignition plugs. Keep the wire from dropping into the undertray by inserting it in one of the slots in the burner supports. Remove the three screws securing the dual ring wok burner. Remove the wok burner base plate. Lift the ceramic tray from the hob. Note: Each regulator shaft is equipped with a black ring. This ring may cling to the rubber seal in the ceramic tray. Check and remove the rings from the rubber seals. To order parts, call 1-800-245-8215, 8:30 AM to 5:00 PM EST
I will explore first suggestion thank you, but will need to remove undercounter oven to expose the underside of the hob. Will update response then and thank you for taking the time to respond, very much appreciated
