Message But may have left out a troubleshooting step.

From the sound of it, your fuel pump check valve is working (maintaining pressure when the return is closed)

I would replace your FPR and/or pulse dampener and test again (your FPR seems like the culprit here).

Plug... I have spares of both for sale...
