On some vehicles the speed and reference sensors not only indicate when the crank and cam are at specific positions to fire the spark , these sensors are also used to fire the injector pulse for the fuel injectors.
If someone knows ( probably Loren ) if that is the case in the Porsches and which sensor does what , it may give you a bit more information since you say you are smelling gas ..

A DME needs both to do either function.
There is no cam sensor, the distributor routes spark to the correct cylinder.
The sensors tell when the crank is at a specific position (reference ) and how fast it is turning (speed) this sensor also tracking position and speed variations during each revolution.
