Crank Sensor Issue? I started a previous thread about my car not starting, I didn’t think anyone would read my question on that thread so I am starting this one specifically about my crank sensor.
https://ls1tech.com/forums/pcm-diagnostics-tuning/1959445-help-please-won-t-start.html
I purchased a new Delco Crank sensor and did a little bench test on both, they seemed to register an output voltage at the same time I moved a metal tool in front of the sensor but the old one gave a 4.76V output signal and the new one gave a 4.93V output. Everything on the test setup was identical. Would that small difference in output voltage mess with the computer and possibly cause the engine to not start?
I will probably just end up changing the sensor and try starting, but I wanted to see if any of you have seen this and know the answer. Thanks!

Thanks for the response, found the issue was a bad Primary VE table in the tune file. Something glitched and the file had maxed out values in every cell, I am running a speed density tune, so it was dumping max fuel at all times. Fixed now and running.
