We had a number of cars come in to the shop for this back when... The car never not started, nor did it run any differently..
I think the only car we were actually able to diagnose had a leaking PPRV (positive pressure relief valve) which let the fuel pressure leak down when the car was shut off, rather than hold it in the fuel rail
Personally I wouldn't worry about it
