If you have a look at the provided link you will see that a digital chip would draw current from their Vcc pins mainly 'by burst'. It's the switching of the internal logic that create theses current pulses. This happens, regardless of the used oscillator. If you don't have decoupling capacitors, then the 'quality' of your Vcc would depend on the length of your Vcc cables, quality of the breadboard contacts, kind of power supply you use, etc. Use decoupling caps and if 5V is provided, the power won't be an issue anymore.

(as a fist order approximate). – Jul 23 '14 at 10:47 •. Your code sets the PIC to use MCLR reset but you have nothing pulling you MCLR up to vdd. AFAIK the PICkit2 wont pull it up to vdd but will simply release it. You can add an external resistor pulling your MCLR to Vdd or you can try your code with: --- __CONFIG(FOSC_INTOSCIO & WDTE_OFF & PWRTE_ON & CP_OFF); +++ __CONFIG( FOSC_INTOSCIO & WDTE_OFF & PWRTE_ON & CP_OFF & MCLRE_OFF ); I have to point out, even though it may seem basic to some, that LEDs cannot work in reverse, if you are not 100% certain that you have the polarity correct, try reversing the LED (very few LEDs have maximum reverse voltages lower then 5V so this should not be able to damage the LED or the PIC). Also, dont forget to power your circuit. You have to explicitly tell the PICkit (especially the PICkit3) to power the host circuit otherwise it will assume the circuit has it`s own power supply and it will not feed power to your circuit.
