Autodata states 5.0bar minimum delivery pressure and 2.3-2.5bar at the rail with vacuum applied. This is the spec for XR2i Fiesta CVH EFI as Escort '86 isn't on there anymore.
Was a known mod to raise pressure to 3.5bar to stop light throttle hesitation back in the day.

Yeah, there are some tests.
Depends which sensors you need to test.

Well I have a three pin fault code reader on it's way so will see if that comes up with anything.
Actual pressure we got off the pump (via popping a gauge between the fuel feed to the filter banjo) was 4.0 bar so we are not that far off there.
We took a reading from the return of the Fuel Reg and that came back as nothing (despite adjusting the screw) which leads us to think that the reg might of had it
