Hi all,
I recently had a minor incident and it caused the car to stop starting, I’m almost certain it is some kind of fuel cut off switch as the car turns over but does not start, I can’t hear any type of fuel pump prime either. I have looked all over for a physical switch so I thought I would come to the forums for some advice

Check your Owners manual - only works if your Fusebox
in the Engine bay - looks like the above.​

They changed the Fuse-box layout - back in 2013...
As to which relay is vague in the Owners Manual

Schematically - the Relay is in and on the Engine Bays Fuse-box, but as to which one - use a continuity checker to locate that Relay by probing F11 Fuse terminal to the Relay that takes the power from that Fuse on the Common of the Switched side of the relay.

Yes, there are no fuel shutoff switches - or breakers - in a Fiesta - POST 1999 - because of the SRS system helps control the Fuel Pump by "talking" to the system and the relay is then controlled by the communication established by the SRS system as a fully engaged talkback system even looking at the Speed Sensors to help with Traction Control.

So if all else works then the Fuel Pump and it's wiring underneath the rear passenger bench seat - are suspect.
