    Toyota Prius P3190 poor engine power, P0A0F -204 ENGINE FAILED TO START Solved, I had these above codes, so I thought I’ll share this video with everybody, the vehicle sounded like it needed a head gasket or an engine, but all it needed is fuel pump. I made this video to help everybody. Search for this video in youtube "

    So the engine essentially just run out of gas permanently No I don't guess it can run. But I guess tec stream I would think should show you that the fuel pump isn't pumping isn't that right?

    One point to remember is to NEVER drive ur prius when the fuel is too low.
    The fuel pump is located inside the tank and needs to be submerged to stay cool. If you drive for too long with low fuel, it will start to deteriorate

    Doesn't tec tell us about fuel pump? I mean it is one of the first things you're supposed to check on a nice engine for running and running problems fuel and fuel pressure need to be relatively close or in the range the Toyota gives for the fuel pump which is pretty decent most Toyota in tank fuel pumps for EFI have been the same pretty much since the mid eighties I use a Toyota EFI fuel pump in one of my motorcycles It's the same pump.
