One thing you shouldn't have done is start by disconnecting connectors. You shouldn't use any oil based lubricants in electrical connectors or connections any how. Use electrical contact cleaner or Deoxit.

The first step would have been to scan the engine computer for trouble codes to find out if there are any codes stored that are related to your no start. You probably generated a bunch of codes by unplugging things, so reconnect everything and clear codes. Then rescan to see if anything is stored. Write down the code number(s) and post them in here.

Another technique to use to troubleshoot a no start is to use this handy guide to figure out what is missing or not functioning properly:

Re: 2005 Nissan/ Datsun Altima wont crank Sign In

The P0340 is a problem in the Cam sensor circuit. The other codes are all associated with the "Drive by wire" electronic throttle system. They could also shut the system down.

I would probably clear those codes and see which ones come back.

I HAVE CONFIDENCE IN YOU GUYS AND MY SELF I AM A TV TECH AND I AM ELECTRONICALLY AND MECHANICALLY INCLINE TO A PONIT THANKS AGAIN DON'T LET MY KILL ME. WILLIAM i tried to send an attach file but i am unable

Not sure how you fixed a Cam sensor code by changing a Crank sensor but if it worked, great. I would clear the rest of the codes and see what comes back.

Might want to figure out the no crank first. There are no PCM trouble codes that will cause a no crank situation. Need to troubleshoot the starting system first and then tackle the trouble codes.

Is this automatic transmission? Does it have an aftermarket alarm system? It should have NATS (Nissan antitheft system). Is the security indicator on while trying to crank the engine?

Why are you guys going after the cam sensor if you can't get the starter to crank the engine?????
