Car has had new pump, 2nd hand injectors, regulator/ pressure switch.
When I got to the car, rail pressure rises on start and engine cuts out. If revs are kept above 2.5k the pressure expected and actual pressure difference can be kept below 45Mbar and engine will run.
Checked injectors for small leak off all the same, coded injectors in as they were all at *******
Owner bought car like this 2 years ago! so I have no history on it.
Cant see anything the garage have missed now injectors are coded, except I cant find a listing for P0070-71 on this engine, so am wondering about software or ecu fault?

Any thoughts please?
