VDD/5v is going to MCLR. The hard thing is I can't figure out the 'state' of the pin when it doesn't start because right when I touch the scope to the MCLR line the damn thing starts, lol.

In your case, what voltage are you feeding MCRL with? Are you sure you are getting this voltage at MCRL? Try replacing the 4.7k resistor also. Try connecting an inductor in series with the 4.7k resistor or a 0.1uF capacitor from MCRL to ground close to the MCRL pin to eliminate posible noise.
