No the car doesn't have a crank sensor for the ignition. The control unit reads the induced signal from the impulse transmitter in the distributor. You pretty much have to have a scope to view its output.

By placing your test light on the negative side of the coil you should see a blinking light while cranking. if you see a solid light then the coil is never being connected to ground.
