Mine always trickles a little bit of diesel back to the WVO tank through the purge line (when im burning diesel) .. Im pretty sure that's normal.
Can you hear the pump running? is it getting power?
Do you have a fuel pressure gauge?
Get up to temp, shut off the truck, flip switch to manual and see what the WVO pump is doing.

That's what Id do at least...
