Various circumstances that make your Ford Focus stall

Why does your Ford Focus stalls when driving ?

Another essential part, which can often be the cause of engine letdown, is injection.

Also, a pressure sensor with an incorrect information delivered can disable the entire system on your Ford Focus.
In addition, it will also be necessary to check on the fuel pump side. If your engine no longer receives fuel, there is no combustion and it is not able to provide the car with energy.

Electronic components of your Ford Focus

Let us consider now an electronic failure on your Ford Focus that makes your Ford Focus stall while driving. On your electronic circuits, a part may be barely damaged and as a result have a poor current flow which will have repercussions on the whole vehicle. A simple example: the ECU, which is an essential part of the electronic circuits, will lock up and can pass this on to the engine, resulting from a shutdown. As regards the ECU, your BSI Box, which allows precisely the ECUs to communicate, can perhaps be the origin because, as explained earlier, these parts are essential and could make your car stall. A slight defect may affect the engine and provoke it to shut down on your Ford Focus.
Be careful though, we recommend you not to proceed to the replacement of this part yourself, because it is specific to each car. It is therefore necessary to ask a professional to do it .
What about the alternator ? It is one of the parts that project electricity into your vehicle and as a result if it no longer works, other parts may not be powered, such as the computer. If not the alternator, the battery could be the cause. It supplies power to your Ford Focus and therefore in the event of a failure it would have the same consequences, your car will stall.
