extruder problem

[hakem]

hi
i have a new geeetech i3 and i assembled it correctly and everything is working correctly except there is no filament coming out from the nozzle ,
first i think it was the extruder motor and the heat but i use 250c for the abs and i tested the motor with out the filament and with the filament without the nozzle and it works fine.
second i dissembled the extruder and heated it and try to push the filament with my hand and nothing goes out as you seen in the picture attached

The hot end is block. Please use a thin copper wire to clear it.

i used and cleared it many times and nothing

When you take the hot end apart like this, can you see any light through the hole?

Do you have a needle? Please use a needle to clean the hot end when heating.
