This would be a leaking fuel pressure regulator or injector.

You'll have to hook up a pressure gauge while your key is on/engine off.

If the pressure doesn't hold steady for at least 15-minutes, then something is leaking.

Pinch off the fuel return line from the FPR back to the tank. If this stops the leak-down, then it's the FPR that's leaking.

If pressure continues to bleed off, then it's one/more of the injectors.
