A fuel supply and injection system comprises a fuel tank, a single electrical pump unit in the fuel tank, fuel injection valves secured to an engine main body, and a piping arrangement, which connects between outlet of electric pump unit and each fuel injection valve. Each fuel injection valve includes a nozzle for injecting fuel directly into corresponding combustion chamber. A fuel supply and injection system comprises a fuel tank, a single electrical pump unit (35) in the fuel tank and including an inlet (34) and an outlet, fuel injection valves (45) secured to an engine main body, and a piping arrangement, which connects the outlet of the pump unit and each fuel injection valve. Each fuel injection valve includes a nozzle in a corresponding combustion chamber, and injects the fuel supplied from the pump unit directly into the corresponding combustion chamber. The single electrical pump is the only pump for supplying the fuel to the fuel injection valves. An Independent claim is also included for a method for controlling a fuel supply and injection system for an engine of a vehicle, by supplying electrical power from a battery of the vehicle to an electrical pump unit at time of start-up of the engine, and supplying electrical power from the battery to a starter to drive the starter for starting the engine.
