Generally starters get the ground from being bolted to the block. Is this not so??
In Volvo world (generally a car is a car no matter the brand) The key in the ignition is then turned activating the differing circuits (15, 15l, 30, and X-supply) as the key is turned from Positions I, II, and III. The immobilizer interrogates the key (even though they're laser cut, the antenna ring outside the ignition lock cylinder receives the signal from the key and sends to the immobilizer. Immobilizer then sends the signal to the ECM to power the starter relay thus supplying power to the starter motor. This is all Volvo speak though. Is it not the same or at least similar to Crossfire speak??
