The priming device (2 gallon bug sprayer) has two purposes in a case like yours.
The first is that pressurizing the intake side of the filters guarantees that the filters and lines up to the injectors will be full of fuel.
The second is that it eliminates the fuel supply line and its potential failures as the culprit.
If it runs on the bug sprayer supply, but loses prime when you reconnect the fuel line, then you know the problem is between the tank and the fuel filter.
Your comment about the priming button not firming up could be a clue. That may be that the priming mechanism itself is leaking air, and that is the problem. Or it could mean that the fuel line is leaking air or blocked.
Regardless it’s a guessing game that sends you down a path of maybees. I am sure there are other ways of diagnosing this problem. I have proposed one that will provide definitive data.
