Connection problems of esp8266

As soon as I am connecting 3.3 v from Arduino to ch_pd and vcc of esp8266, the port connected to Arduino becomes unavailable. Can you let me know how to proceed. I am using pin 2 of Arduino to tx of esp8266 and pin 3 to rx.

ESP8266 require much current. Maybe regulator of arduino is not capable of powering much current and thatswhy its output voltage drops when you connect ch_pd and vcc. Try using another power source.
