This is something that, when research is done, is becoming more and more prevalent in today's auto market. Mfgr's are/have moved to GDI (gasoline direct injection) engines for more efficiency and power from the smaller engines they are throwing in cars. Those GDI fuel systems are under VERY high pressure! Most of the traditional MPI (multi-port injection) systems that have been on the market for the last 30 or so years since carburetors operate at a fuel pressure of around 25-30 psi. That's similar to a spray bottle. The fuel pump on the tank does all of the work from tank to injector. When the tank pump goes out, the car stops completely.
The new GDI systems are slightly different. They operate at fuel pressures around 2,500-3,000 psi. Literally 100 times higher!!!! That's similar to a motor driven pressure washer! The pump on the tank now has the easy job of just sending the fuel to the engine compartment. These GDI engines now have a SECOND fuel pump that takes that fuel from the engine compartment and cranks the pressure up and then blasts it through the fuel rail and injectors directly into the combustion chamber. It's these hard working, high pressure fuel pumps that go out on occasion. When this pump goes out, the car is still able to be driven to get you to the shop.
