When you pull your fuel filter does any fuel come out of the lines going to the rail and from the pump? If nothing comes out from the pump side then for sure it is time for a new pump man

Turn the key on, engine off, then do it.
$20 fuel pressure gauge.
I have one, works well, correct schrader valve hose.
