1910, Adams Farwell of Dubuque, Iowa, USA.
Commercially, used only on diesel engines (CI) till after WW2.
First common FI use was in German aviation gasoline (SI) engines, starting just before WW2, when Germany's Robert Bosch company's Dr. Lichte, developed a fuel injection system for aviation use that increased power or decreased fuel consumption about 3% on the Jumo 201 series engines.
The mid to late 30's, fuel injected Jumo 201G and the 1935 Daimler-Benz DB 601A-1 engines were used in the famous ME / BF 109 fighter plane series.
The Bosch developed systems had 14 different fuel pumps.
fuel injection as we know it now was invented by german ingeneers
If you cannot get gas to the fuel injection system, you may have a clog. You can have the system looked at and flushed out and take it from there.
Carburetor, mechanical fuel injection, throttle body electronic fuel injection, ported electronic fuel injection,
kgjhbv
Carburetors and Fuel Injection... also direct and indirect fuel injection.
Sequential fuel injection is a type of ported fuel injection, yes.
M.P.F.I. Multi Point Fuel Injection. This is a fuel injection system for gasoline engine.
Yes it does. It has TBI / Throttle body injection, Fuel system.
Fuel injection systems do not need to "bled." However, if Questioner is actually trying to ask, "Should I relieve pressure in a fuel injection system before performing fuel system maintenance?" then the anwer is yes.
Yes it is a TBI / Throttle Body Injection. Fuel injected.
Throttle body fuel injection.
Electric fuel pumps
