[s-cars] WAS CEL came on while driving, won't restart NOW Won't start at all......

[Tony Curran]

Dave, 
 
 I had the CEL and intermittent problem with thrown code. Here's how I fixed
it - copied from post from two years ago 
 
 First, I was able to remove my CPS without removing front of car as  I've
done the Monster Air Intake mod that removes the stock air intake  snorkel -
a 24mm socket fits right in the space left behind once the cam belt cover is
removed. The original Bosch Hall sender device (HKZ101) is now out of
manufacture. I had started to investigate an alternate part (part no. 2AV54)
but have not progressed. But I did find the HKZ101 is used in Volvo
distributors of the mid-80s (probably Audis too). I actually bought a 1988
Bosch Volvo distributor from a Euro car wrecker in Ottawa for c$50, then
transplanted the Hall sender to the S-car CPS  mount plate and spliced
wiring. Has worked floorlessly for about 10 months now. 
 
 It has continued to work flawlessly since. I do have a couple of alternate
devices on shelf procured during GB #2.

 96 S6 - now doomed to have a CPS failure...

Tony: That would seem to make good sense.  Now tell us about the Volvo CPS.
Complete bolt in or ??
