Well the first issue is in how much the person who is looking for the mechanic knows. If you know nothing then you have no way to tell if he's a BSer. With what you described, the first thing to do is check the fuel pressure. More modern vehicles went from mechanical fuel pumps to electric in tank pumps. During normal operation you can often hear the pump when you just turn the key to run but don't crank it over.
That doesn't prove that there is proper fuel pressure or VOLUME. Pressure can be tested at the Schrader valve. Volume can be tested by removing the valve core and seeing how much volume the pump can deliver in X amount of time. People will often assume that the pump is good while only looking at pressure. You can develop pressure yet have low volume.
So it sounds like he could be on the right track but.....
