[Shotimes] CPS Failure Mode Confirmation

[Erik Balser]

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?
