boxster cranks but won't start..help!!

The DME isn't receiving a signal from the crank sensor. Either the sensor has failed, there is a wiring issue or your DME has failed. Also could be possible the flywheel has lost a significant portion of its teeth but that is pretty unlikely.

To test the sensor, disconnect it at the motor and measure across pins 1 &2, it should have 0.8-1.0 kohm resistance at around room temperature (20 C). Across 1 &3 it should be open. If not the sensor is bad.

If the sensor is OK you need to test the wiring between it and the DME.

Leave it to a "Master" to come with a logical conclusion. My friend's 3.2 DME 911 died a similar death; culprit was the crank sensor.

You learn a lot from these boards; not that I can remember it, but it's always a great resource.
