Bake burner

Question

broil and bake use a glow plug for ignition and both work fine. Broil will light but bake does not get gas. Gas valve has been replaced to no avail. Is it possible the contacts for the bake are not making?? Should the voltage from the controller to the valve be the same for both broil and bake, because broil is getting more voltage than bake leading me to think the contacts are not closing completely. Thoughts???
