I have a PIC12F675 that I need to program. I'm using a Pickit 2 and the Pickit 2 software. Supposedly I should be able to program it using this circuit, but the Pickit 2 software is not detecting the chip at all.
What's going wrong?
EDIT: I've added an image of my circuit breadboarded out. And here is where you can find the datasheet for the PIC12F675. Skip to page 4 for the pinout.
EDIT2: I just actually looked at the chips (dumb, but I kind of assumed mouser would send me what I ordered), and I noticed they're actually PIC12C671's. How much of a difference would this make?
Final EDIT: Wow! Thanks to everyone that helped me with this! I was not expecting this kind of response. It ended up being a small stupid problem just like I thought it would be. It was my fault for not double checking everything when I received the package from Mouser.

A possible problem is that some PICs need a power-cycle to get into programming mode. The 12F675 in particular needs this when the configuration word in your application configures the MCLR pin as GPIO.
When the pcikit2 powers your target chip it will provide the power cycle. With the independent +5V you supply it can't do this.
After covering the most probable problems you might go for the improbable ones... Don't laugh at me, I am drawing on my own experience!
In response to your EDIT2: ROFL, check my bullet 4. The PIC12C671 is a totally different chip, and the C means it is an EPROM (one-time-programmable) chip, which is not supported by pickit2.
