Presumably “there wasn’t any” with the the fuel pump fully energized? See, if there wasn’t any fuel pressure at all - as in zero psi - then the car would never run at all - even a little bit - for 5 seconds or 1 second. So hopefully he didn’t just stick the pressure gauge on and that was it. My car has been sitting a couple of days (hasn’t needed to go anywhere) and I’m sure the pressure is probably zero. A few cycles of the key will pump it up to spec.
Does the fuel pump run when the key is turned? If the fuel pump runs but you get little to no fuel pressure, then you replace the pump. You you turn the key and pump doesn’t run at all then you check the electrical supply to the pump first - including relays/fuses.
