These two posts may give some help. The first points to the simulator documentation from the author and mine sort of describes in not much detail how to get in to debug mode.
Hello!
Maybe there will a simulator soon. I made a super basic one which has been merged in the Fritzing repository (in its own branch), but it has not been merged in the development branch. If you are able to compile it from source, you can try out. If not, you will have to wait until is released (hopefully in 0.9.9, but I cannot guarantee that). It still needs some work and it is an experimental (beta) feature, but it is functional.
HOWEVER, the simulator is really limited and it will not be…
I think one problem is likely your resistor value on the LED is too high. As it stands at 9V it will only put about 1ma through the LED and LEDs typically need 10 to 20 ma to light, About a 1K resistor should get you to 10ma.

That said I still can’t get simulation to work even in debug mode with transient selected (you need to start Fritzing with the -d flag to enable debug mode then select the transient mode (greyed out here because debug isn’t active)

in order to get…
