Hi there,
SUDDEN cut out and no start will not be fuel pump.
The ECM controls the fuel pump relay, it also controls the injectors.
It does not the fire the injectors, if it does not receive a crank position signal.
The car would have logged a DTC for the cutout condition.
A scan tool will tell you the DTC.
It will help you to know the DTC set.

So it sounds like crank position sensor is most likely?
Subaru Mechanic: Gary, ASE Certified Technician replied 3 years ago
Could be, but a scan tool will verify whether the ECM is seeing the signal.
Without a scan tool to look at data, you are guessing.
You could take a punt, but it really needs a little more experience.
