[V8] Engine Speed sensor???

[Scott Simmons]

No tach bouncey bouncey = no RPM signal.  It should flutter a bit at the 
base.  No fluttering means the tach isn't getting a signal from the ECU.

But usually the sensors work better in the cold...........

Also, I've been told to never, ever, ever use ether/starting fluid.  
Have been told it dries out cylinder walls?
