Same Problem I have a 99 SS with an LSX 383.. (how I purchased the car) The tach has not worked since I bought it.. cam sensor has been changed (so I was told) but I have a feeling the crank sensor is the problem.. unfortunately there were other issues I found after I bought the car which were not disclosed and appeared as if they were attempted to be hidden.

Without that crank sensor you wont be running. Computer wont know when to fire ignition so I don't think there's any failsafe for that. cam sensor is just a 1x so that tells the computer whether its on intake or exhaust stroke. If its not reading anything on tach but engine is running I would look at either dash / dash wiring / or tach output from your pcm

Launching!
On a '99 it's not just the 'pull-up' resistor?
