Clutch Start Cancel Not Working

If I push the button and let the clutch out the vehicle will stall. I am pretty sure I'm not doing anything wrong, I'm not moving, I'm in 1st gear, and I have the clutch in when I push the button. The switch itself has the light come on, but it doesn't hold the clutch, it will let the engine stall when I let the clutch out.

What should I look at first?

Edit: wait I might be an idiot, seems like the purpose is to let you start the vehicle without the clutch in, not have the clutch in and then push the button then release the clutch.

 

I have to question why you would want to start your car this way to begin with. You either push the clutch in and start the car or push the cancel button and start the car w/o engaging the clutch. In either scenario the transmission should be in neutral.

 

Its for when you are off road and you cant afford to roll back. I would just pull the e-brake if I couldn't afford to roll back because that seems like a better part to wear out than my starter motor

 

I am still not tracking in this scenario. Why is it necessary to press both the clutch and push the clutch cancel button?

 

It's not. You can push EITHER the clutch in, or ignore the clutch pedal completely, and press the clutch cancel switch to be able to start the truck. Only limitation on the switch is that key has to be in the ON, or RUN (same thing, ON/RUN), position to be able to activate the switch. So, turn the key to on, make certain the transmission is in neutral, or the truck will move when you crank the starter, press the clutch cancel switch, and then crank it over.
The position of the key doesn't matter if you're going to use the clutch pedal. As long as it's pushed in before you turn the key to the STArt, or crank, position. If not, the starter just won't turn.
Actually, that's a kinda handy feature. If the truck hasn't been run in a while, so the fuel system is drained out, when you turn the key to start, without pressing the switch OR pressing in the clutch pedal, the fuel pump will run. Let it run a few seconds until the sound of the pump changes, THEN press the switch or pedal. That way the fuel system is fully pressurized, and when the starter turns, finally, the truck will fire right up.
It's a handy way to check the fuel pump without having to use the test jumper to make it run, too. As I said, you can hear the fuel pump run with the key turned to start, but the pedal or switch not pressed. Tells you half the COR, and the wiring, as well as the actual pump, is all working properly.

Does that answer your question?

Your edit is correct, it can be useful offroad. Both keeps you from rolling back when restarting after a stall, and if you're on a slick surface it can be easier to start moving. Putting the truck in gear and releasing the clutch can break traction, but slowly introducing torque while in gear, with the clutch already out, can give you the slow start you need to not slide backwards
