Quoted from Zolzar:

The coils fire just fine when grounding the metal tab.

Useful info...this means that the coils, diodes and wiring correct !

Whats wrong ? )
If I understand correctly what problem is, I suppose that is bad 2N3055 and/or MPS-U45
(Assuming that the correct (1Kohm ?) resistor on MPS-U emiter ..."shorted" or similarly,
aka "ground-moded" )
