fuel flow will get stopped then engine get off
It would depend on the vehicle. If the vehicle has a carburetor, the pumping action primes the engine with fuel to help start the engine. If the vehicle has fuel injection, pumping is not required.
This engine is electronically fuel injected.
The difference is how fuel is introduced to the engine. A carburated vehicle uses air flowing past a series of valving to suck fuel in to the engine mechanically. A fuel injected vehicle uses fuel injectors controlled by a computer. The computer decides when to open the fuel injector which then shoots a burst of fuel in to the engine.
You can prevent fuel injection flooding by not pumping the gas pedal when trying to start the engine. Fuel injection systems do not need any additional fuel when starting the engine.
fuel injection
On a bosch CIS or CIS E fuel injection system there is a thermal time switch located on the engine upper radiator coolant hos at the head. This device controls the cold start injector timedto engine temperature, cold engine up to about 10 seconds of injection, hot engine 1 or 2 seconds of injection. This switch is used on many European models (VW, MB, etc.) Since you did not provide a make, year and model of the vehicle this is only a guess.

well , it depends on your engine type .. If you are using an older vehicle (an engine without MPF-i (fuel injection)) , nothing will happen , the car will just burst to a start , that is all.. But if you are using an engine with MPFi/Fuel injection , it may damage your fuel pump , so it is recommended that you start the vehicle on idle. unless if your car is not starting , you may need to step on the accelerator just a bit .. note : If you are having a K-Series Engine , The engine may quickly jump to 6000 rpm if you raise the engine while starting , and that may damage your emission and fuel injection systems

thr fuel filter is under the vehicle follow the fuel line from the fuel tank its on the fuel line that runs tto the front of the vehicle to the fuel injection a metal cylander about 3 inches long with brass threads for the fuel lines open the gass fuel cap and let the fuel pressure out before you work on it
