Where is the fuel rail sensor located?
A fuel rail pressure sensor (commonly known as a fuel pressure sensor) is used in many diesel and some gasoline engines. This sensor is usually located near the middle of the fuel rail and is linked to the engine control unit (ECU), which is the central computer of a vehicle.
What is the fuel rail pressure sensor?
The fuel rail delivers fuel from the pump to the injectors, and the rail pressure sensor measures the pressure in the rail and sends a signal back to the engine control unit (ECU) indicating the current pressure in the rail.

What happens when a fuel rail sensor goes bad?
As the fuel pressure decreases, there is an electrical signal sent to the fuel pump to demand more fuel pressure. When a fuel rail pressure sensor begins to malfunction, there are some primary symptoms which alert you that there is something wrong. There will be difficulty starting up, making the starter engaged for a longer time than normal.
