pull some plug leads and it won't start.
This is not such a good idea, as the ignition secondary voltage will become extremely high, and quite possibly cause expensive damage to the ignition system.

There is also the problem of the unburned air/fuel mix being pumped into the exhaust system while test-cranking the engine; this can result in a catalytic converter fire or a burst catalytic converter/muffler on a subsequent start attempt with the ignition wires reconnected.

Disconnecting the fuel injector harness would be a much safer option.

Good news! I FINALLY found the PLUG (not switch) to disable the fuel. Now what would be my next step in all of this, sgtwookie?
