I would get the codes read any significant engine fault which puts the engine light on can also trigger ESP/ABS fault or visa versa. Without the codes it would just be wild guess work

Sounds like the fault is with ABS/ESP then as the engine light came on later the engine code will be a CAN error no speed signal or similar. So you will need scanner to read ABS for faults

Just don't forget injectors are numbered from gearbox end not cam belt end on peugeots

Likely to require coding as the later ones have specific codes which details injector performance. older ones where just had a group coding so where easier to match.

Have you checked wiring to injector etc

A good recon from a reputable company should be fine. Should be fine with the ford injector
