Pretty sure it uses the same Bosch motronic that porsche uses - I recommend getting the service manual and following the trouble shooting guide. a no start can be anything from a simple relay (and on my car there is a $30 DME relay under the driver's seat that goes bad - carry a spare)to distributor to coil.
If the car will turn over it probably is not the starter.
