Spins like a good un, fires with cold start, but doesn't start. I'm thinking fuel pump or supply to pump (relay/fuse?) - where do I start looking? Or has someone here seen this before?

fuse 28 powers the fp relay r9 if the fuse is blown then the pump has probably died. Some fiestas have a collision switch behind the glove box that can trip with a speed hump. connections to the pump can corrode too.

On my mk5 (or is it mk6 - I was never sure), you can hear the fuel pump make a faint buzzing/humming noise for a second or so after turning on the ignition, but before turning the starter motor.

you should be able to hear it, if things are quiet.
Last week I took in a customer Focus for MoT, while I was in the car, on the ramp, engine running, checking the lights, the engine died: dead fuel pump, fuse blown, we put in a new fuse just in case, and the fuel pump would just make a slight clonk, but no whirr. A new pump went in and away it went, this is the third one I have had to change on a focus, and it is not a fun job.
So they can literally just die while running, although death when you first try to start or after being left standing for a while is the usual trick.
