tesla coil not working :(?

hii.... a few days back i constructed a tesla coil .... the spark gap fired ... but there was no activity in the secondary ... no sparks or anything ... :( ... please advice me ... what could be the error ??

i tried tuning by changing the taping of primary ..... but no effect ...

Nothing doesn't seem right there's not even an arc to a screwdriver or illumination of fluorescent lights on top of it? If not then I don't know if so then what is your tank capacitor and power supply?
Check for a shorted turn on your secondary, run the primary off a small signal generator.
