I suggest you to try with another chip of same and different type both. Just to make sure your PICKIT is fine. PIC is not able to detect your device its clear.

It is *NOT* reading successfully !
There is no sign that anything is working.

Post a diagram of the board the PIC is mounted on while being programmed.
Mark all the connections to the PICKIT3.

Remove all power connections to the circuit at the end of the board.
Remove the grey wire next to the 10k resistor.
Use a meter to check you have 5 volts between pin 8 and pin 20.
If you have 5 volts, try to read the chip ID.
Report back your results.
