Crankshaft Position Sensor

Needless to say I was not happy as I was late for work, late getting kids to school.
The good thing is there are quite a few peace officers and people out there willing to help a disabled vehicle maybe because it is a 1997 (Red) TransAM WS6 or they are just being that generous.
I appreciated there assistance but already made the call to road side assistance.
While I was waiting pulled out my laptop and ran Pro Scan only to find that I have the following codes.
DTC P0335
Crankshaft Position (CKP) Sensor Circuit
DTC P0336
Crankshaft Position (CKP) Sensor Performance
Has anyone experienced these codes? What were the symptoms prior to the failure?
I will be replacing this part this evening as I have already ordered a replacement from NAPA but curious as to what I could have done prior till as a preventative maintenance.
Warm Regards,
Bruce
I tested the fuel pump and it passed. Being the engine is turning but not starting I am looking at the ignition system. If someone has any advise to offer I am open to ideas.
