The magic button: how the fuel pump switch works

Electronic car systems are both a gift and a bane for drivers. The car is now like an on-board computer, and you can find out about the state of its "stuffing" instantly by looking at the screen. In this flow drivers often study only the basic basis of car functions (it is true, the manual is like a textbook of quantum mechanics), but often it is only a step to problems with the car. In this chaos, many don't even realize that there is, for example, a gas pump button - we tell you why you need it and when to press it.
Note that many novice motorists call a tow truck without knowing about the fuel pump button. So, the button's sensor is often triggered inertially and without the driver's participation; after braking the car, of course, does not start. The motorists take their cars to the service centers, but it is possible to fix the car by pushing just one button. You can learn more about this mechanism if you study the vechicle specifications.
Such button is needed for emergency situations and emergencies: for example, there is a fuel leak in the car; the driver understands that he is in danger of fire or explosion. In addition to the magic button itself, most often the car is equipped with an inertia sensor: it is quite entitled to decide on its own when to trigger. Most often it is a sharp braking of the car or a road accident, the latter the sensor is designed for.
The sensor is located next to the main airbag, but as we have already found out, often the sensor is triggered for no reason. 
Such a mechanism can be compared to an automatic circuit breaker, when a short circuit occurs in an electric circuit breaker, and to avoid fire, the electricity supply is limited, but as soon as you put the breaker in the switchboard back in place, the electricity is supplied to the house.
Button to turn on the fuel pump can be found in modern cars in different places, here the instruction manual will help. Let's remind: the sensor is located more often behind an airbag together with the button.
When the car does not start for unknown reasons - check the gas pump button. But there are scenarios, when a tool, meant to cure, destroys: it happens with petrol pump too. To check if the button is working - randomly turn on and off the gasoline supply to the engine. Reduced pressure goes to the car's computer in any case. Frequent errors of this problem: "P0230", "P0005", "P0006", you can learn more about the car troubles here.
In case of repair, the button and the gasoline pump sensor are easier to replace than to repair.
