A few weeks ago I bought a 1993 SAAB 9000 CDE, non-turbo, I got a
good deal because the previous owner said the engine dies when you run
it for more than about 20 minutes at normal engine temperature. He was
told by a mechanic that it is a crank position sensor malfunction.
 The car runs great most of the time, but once in a while (every few
days) it just dies will not start for 20-90 min.
The car does seem to run a little hot, with a lot of range on the
gauge. This might be normal, the car is new to me and it is my first
Saab do I'm not sure what is normal. I did replace the coolant
thermostat with a new OEM Saab one. This did not make much difference
in the temp. The car does usually die at a normal operating temp (half
way up the gauge).
 After listening to quite a few people's suggestions as to what the
problem likely is and inspecting the crank pulley , I hope we have
correctly diagnosed the problem  as the crank pulley and or sensor. The
crank pulley has over 50% of the rubber gone, and it is very loose. I
have bought parts and am ready to change them out, however the wire
from the sensor disappears into an area behind the alternator and below
the intake that I can not even see into, much less get a hand into. Can
anyone advise me on routing the wire and hooking up the plug?  This
can't be as difficult as it looks. From which direction should I
approach this? What must be disassembled to get to the wiring and plug?
Any suggestions appreciated
