The rotation of the pump’s electric motor initiates, and it rotates for a long time to enhance the fuel procedure stress. The PCM timer limits the period of time through which the pump will function before the motor starts off.
On lots of cars the keep-stress specification calls for no lower than twenty psi soon after 20 minutes, but most will engines will get started if tension continues to be favourable though the motor continues to be heat.
In many autos, the fuel pump is situated within the fuel tank. That makes it invisible as you need to just take it aside to find out it.
