No need to connect pin 13, 14, 15 and 16 on the VFD to molex. It's all powered from CN2 connector.
To check if your display is ok;
- take off your datacable
- power it up on CN2
- on CN2 connector short pin2 to pin3 (GND)
that will put the VFD through testmode, if not, then it's likely to be defective.
If it's working then check your wiring or re-cable. Also check your LPT settings.
On the other hand it is NORMAL that nothing happens when you power it up. Only when you start and configure LCDinfo with T23A plugin AND make some screens . But when you shutdown LCDInfo you should get the 'goodbye' message on your VFD, that means your VFD is running fine.
