Do you have to code reset after fixing timing before it'll start relearn crct or

What is your question?

Have correctly set distributor,is aligning with timing marks after replacing all ignition sensors,and replacing coil pack has fuel pressure and still doesn't start or even act like it trying to hit .is it because I need to reset the management system to relearn the new positioning? I have a cheap code reader but it's not throwing up any codes.I have ran out of logical diagnostic sequencing and I could use help with what to check next or what I missed during troubleshoot?

What makes this problem better or worse?

not showing any signs of getting better or worse just stalled out and then compression sounding like the motor kicked half back then timing showed it was past the 6 indication Mark under the distributor cap.

How long has your 2001 Chevrolet Silverado 1500 had this problem?

replaced a faulty crankshaft position sensor that caused it to do one other time before this time
