When you are filling up your car, there is a mechanical device running that causes the gas pump to run. This device is called the idler and is connected to the gas pedal. Whenever the accelerator is pressed while the gas pedal is depressed, the rotation within the idler will cause the pump to move the gas through the system until the accelerator is released. The pump will continue to move until the tank is empty or until you manually press the pedal release button.
The reason that this occurs is because when you take your hand off of the gas pedal, the rotation in the idler causes the pump to turn off and not allow the gas to flow through the system. This can be seen as the engine not being able to keep up with the demand for fuel. When you get into a tight spot where you need more gas, it’s recommended that you pull the plug before you start the car to let the gas flow through properly. Sometimes when the pump is running, it can cause your car to spool over or sometimes it can even damage the engine.
Another thing that causes the pump to stop working is if the car has an automatic transmission. If this is the case, then the car is going to have to be lifted up so that the gear in the transmission can work properly. Then when the car is full of gas, the gas gauge will read full when it should read empty.
Something else that causes the pump to stop working is if the car ran dry. This usually only happens when you have an automatic car. If the car ran dry then you would need to have the car serviced or have the fuel system checked. I am not sure why the gas gauge will read empty if the car ran dry but I will look into that and write that down for you.
Something else that could be causing the car not to start is the battery. Sometimes the batteries are not charging and this can cause the pump not to work. If you keep the battery in the car charged and the car is plugged in then it should start right away. You might just need to have the battery cleaned or checked. In this case though, you will know why the car is not running.
There are a lot of different reasons why the gas pump will not work when your car is not full. Most of the time it’s because something is wrong with the fuel system or the battery. In some cases the problem could be as simple as the cap being off or the lines being clogged. Knowing why your car is not starting is going to help you fix the problem so that you can drive around with less frustration and not as much stress.
