Given that the light on the DS turns on, that says the DS is getting the activation signal, which rules out the pressure switch or code.

Getting a PWM correctly seated in a Spike or Victor is an art. I suspect that is your problem, despite the fact that you tried multiple PWM cables. It may be helpful to get help from a local team that has the touch, if the problem persists.

One other thing I didn't see in your list is measuring the signal from the DS, although I don't think it is likely that this is the problem.
