Why am I not getting an output on my PVX-4140?

Try these solutions:

Be sure there's a jumper on the D-sub connector from pin 12 (interlock) to pin 4 (ground).

Be sure the input pulse is 5 V (TTL level) and is not too narrow.

If you are operating with a single HV power supply, be sure the unused HV input is grounded.
