The oven switch is different in that it is only off in one position of the oven t-stat knob, (OFF), at any temp setting the switch should be on, sending power to the ignition module on the oven reig terminal.
The surface burners are not reig(re-ignite) circuits and spark continously when in the LITE position.
All surface and oven ignitors click when any surface burner is turned on and all surface and oven ignitors click when the oven is turned on but they will only click one or two times, (or until the oven pilot lights - the REIG/re-ignite circuit for the oven senses the pilot has lit by the mill-amps of voltage that will pass thru the oven pilot flame and stops the sparking of the ignitors and only starts sparking again if the oven pilot goes out).
EDITED TO ADD: I was typing this before your last post Matt and the above is a little wrong since there are two ignition modules. If you turn on either the oven or any of the four right burners on, the oven and four right burners spark. If you turn on either of the two left burners only those two will spark since they use the seperate 2+1 module.
If all your wiring and oven spark switch is OK then the only thing it can be is the 4+1 ignition module.
There are two ignition modules, (CTG51 made a mistake in calling one a 4+2), one module is a 4+1 and the other is a 2+1, (first number is the number of manual spark outputs and the second number is the number of reig/re-ignite outputs).
Since you have 6 surface burners they use all of the manual outputs on both modules and only the reig circuit on one of the modules. Both modules shouldn't be bad and if the wires are long enough you could swap the oven spark switch wires from the bad module to the reig circuit on the other module and it should work, (it's going to be a little more difficult then that because the common for the oven is paired with the common for the right four surface burners).
Here's the wiring diagram of the spark switches
You would have to swap the oven spark output ignitor wire(REIG) from the 4+1 module to the 2+1 module then you would have to swap the COMMON-Black#2, MANUAL-Red#3 and REIG-Brown#1 from the 4+1 module to the 2+1 module then swap the COMMON-Yellow#4 and MANUAL-Orange#5 from the 2+1 module to the 4+1 module.
The Yellow and Orange, COMMON and MANUAL on the 2+1 module could be reversed, from the above diagram there is no way for me to tell which would be MANUAL and COMMON but it really wouldn't matter as it just completes the manual circuit for the two left burners.
