it spins an impeller,like a rotating cooling fan with angled blades.the impeller sucks in fuel and pushes it at high speed and pressure into the engine.
It does have fuel injection. It may not be working but it has it. If it is not working then the fuel pump may have failed or the fuse is blown or relay is bad.
If you are asking, "Is there a fuel injection pump in an internal combustion engine with fuel injection?". then the answer would be Yes, it is the fuel pump itself. If that is not your question then please rephrase your question and try again.
1993 sc 400 fuel injection pump location? how do you know if it bad ?
fuel
I doubt that it would be the fuel pump relay. If it's a throttle body injection vehicle, the injector could be stuck. But you wouldn't get ANY fuel into the engine if the fuel pump isn't working. Relay can be tested by turning key on but not starting. if you hear fuel pump 'HUMM', you know pump and relay are working. If no firing at keystart and experiencing flooding, not a fuel pump issue. There is a spark issue of some kind.
The main function of the fuel pump is to pump the fuel from the tank to the combustion chamber at the correct amount and correct time...:P
the fuel pump on most cars with fuel injection is a electric fuel pump inside the fuel tank
Most times with fuel injection it is in the tank and gets changed with the fuel pump.
Yes, a Jerk Pump and a Fuel Injection Pump are the same thing. Unit Injectors and Common Rail systems do not use a Jerk Pump.
If it has any sort of Fuel Injection, it has an electric fuel pump.
Yes, the 91 featured Electronic Fuel Injection and has a fuel pump.
*With Fuel Injection: **Inside the fuel tank *Without Fuel Injection
