These numbers are good for 96 also.
The reluctor wheel used in 96-00 l29 is p/n 12561074.
If these match and the sensor is good, only possible reason could be the space between wheel and sensor.

I measured almost 0.060" of gap between the CKP and trigger wheel. I'm thinking a gap of about 0.015" is where I need to be.Quote:

I just purchased a new Standard Motor Products (PC123T) Vortec 454 crank position sensor and it has an output voltage of 12 volts DC. When the trigger wheel passes the crank position sensors I have the output voltage goes to 0 (ZERO) volts DC.
I did some research and the 454 sensor output a frequency to pcm, and for diagnostics some duty cycle in hz is measured.
It gets some B+ voltage so it is possible the output be around 12v.
For comparison Ls crank sensor output 4-6v signal.
Could a 96-97 lt1 crank sensor be used in the ramjet engine.
The 502 started today, after installing the Standard Motor Products PC123T crank position sensor. More work to follow.Quote:

These CKP sensors are very sensitive to install, I have found that if I install the sensor then use the screw to draw the sensor in they don't work, but if I insert the sensor, then give it a push to ensure its in there flush, THEN tighten the screw it'll start.
