CPS or Imobilizer?

[DarkStar]

Well I got groceries and my car won't start. I'm waiting for a tow truck right now. But it's doing the all good strong crank but no fire. The car threw a pending code for Crank Position Sensor. However I just moved the guts from my key to a new fob, and it's worked just fine.

But, let's say the Imobilizer chip is, not close enough or stopped working somehow... Would cranking it cause a CPS code? Or is the DME smart enough to differentiate the two?

Second, anyone replace the CPS got a pic of its location?
