If you hook up a scan tool (even a cheap one) to the OBD connector,go to the live data's RPM reading,crank the engine and if it shows 100-500 RPMs then the PCM is getting a signal from the CKP and you should look elsewhere to solve your problem.
Those codes point to a problem with the camshaft sensor. I've always heard a bad CPS will make an engine run rough but not shut it down completely. Now a bad crankshaft position sensor will shut down an engine dead in it's tracks.
