pre- igniter went bad. No spark

The trick with any appliance is to remove all the extras,before you get to the problem.Considering that it has electricity, the first step was to turn it off.
After that it was a matter of removing the top burners,range knobs and locate the panel screws that secure it to the stove.Locate the part,remember the colors of where the wires go,remove,replace wires,replace new part with wires,slide into place, and reassemble.
Turn on electriciy and Tada. Success.
