Ignition relay

Which relay do I pull to prevent the engine from starting? I want to be able to crank the engine without it starting. Thanks

I assume you're asking about an '03 C4S.

Per my Bentley manual, the ignition system can be disabled by removing the FIO (fuel injection, ignition, O2 sensor) relay. This relay is behind the rear seat, under the parcel shelf carpet.
Once you get the carpet up, loosen the panel fasteners, then slide relay panel out and flip over to access relay.
With ignition off, remove the FIO relay.

In the color picture, the bottom row has what look to be five relays. From left to right, they are black, green red, white, and white. The FIO relay is the white one between the red relay and the white relay at the end.
