[Shotimes] CPS Failure Mode Confirmation

Ditto - but I've only had mine for 10 months and 15,000 miles.  Changed the
cam sensor last fall, same symptoms, plus it was occasionally difficult to
start, warm or cold.

Sounds like a camshaft position sensor (CMP) to me.  Same exact thing
happened to me when I was 100 miles from home.  Managed to limp it home and
it ended up being the CMP sensor.  ALOT easier to change and also alot
cheaper.  I've never had a crank sensor fail on me but I've had 2 CMP's fail
on my '89 and '95 SHO's. Both times the tach symptom of going to zero
happened, and would intermittently start after stalling.  Also I had a hard
bucking while the sensor was flickering between working and not working.
Good luck.

> After reading of CPS failure for the last 4 years it appears that I now
have one of my own.  I just want to confirm that this is the case before I
replace it.  Symptom is the vehicle will stall (check engine light comes
on), with the vehicle travelling 50 MPH (MTX still in gear) and the engine
spinning at 2000+RPM the tach reads zero.  Car will then suddenly come back
to life and run normal.  It did stall once on a side street and wouldn't
start for 10 minutes.  On this occasion when cranking the tach would read
correctly but the engine wouldn't fire.  Opinions?
