Does check engine light come on or bulb check when first turning key to on position?

Customer: replied 7 months ago.
Checked for codes and found none.
Expert:  Dan replied 7 months ago.

If you used a testlight to verify you aren't getting ground pulse then problem pretty much comes down to crankshaft position sensor or the PCM. Next step would be monitoring crank signal on scantool of possible to see if it shows signal while cranking if not verify wiring between crank sensor and PCM is good then replace sensor. Let me know if you have more questions, thanks.

Checked signal while cranking with scan tool. It showed only 122.
Expert:  Dan replied 7 months ago.

That definitely seems too slow, if engine seems to be cranking over at correct speed then I would go ahead and replace the crank sensor. Let me know how it goes or if you have more questions, thanks.

Customer: replied 7 months ago.
The engine I put in came out of a automatic truck. Tried that crank sensor but still no spark. Is there a difference in the two sensors?
Expert:  Dan replied 7 months ago.

Yes, they do have different sensors.
