the pressure regulator works all the time. It adjusts the amount of fuel returned to the tank as teh car runs, and will cause a hard start situation if the diaphragm inside the regulator goes bad. The regulator lets the pressure bleed off, and teh 2-3 second key on pulse is not enough to get the pressure up where the car will start. IT is a HORRIBLE practice to put gasoline directly into a MFI intake, as it is designed for air only and can cause vacuum leaks at best, and a manifold explosion at worst. You should never have to "prime" a fuel injected engine. as soon as you turn on the key, the fuel pump cycles to prime the system. It would only run a few seconds at best on the gas poured in, and the regulator held jsut enough to keep it running until the car was shut off. I hate to say it, but your friend wasted the money on the fuel pump, she needs a regulator.
