2000 sprinter 311 CDi will not run on all 4
has a strange fault.

replaced full engine
new set injectors
new oil filter air filter etc
on starting runs lumpy as in firing on 3 pots
replaced cam and crank sensors .
has no power and only revs to just over 2k
have fault codes on our texa
P1661 INJECTOR VOLTAGE
PO201 INJECTOR ONE

PO105 PRESSUER SENSOR
PO204 INJECTOR 4
we have swapped injectors around
still same fault
we have 2 spare ecu units and these both give the same fault.
yes we have change keys also
we have run the no one injector out side the pot
this puffs for about 7 times then stops
the engine starts runs for brief moment then runs lumpy
we would be grateful for input
how it runs without the number one injector firing is a mystery but it douse.
hoping it is not crossed with a p38 range rover and Christine
help please.
going on the assumption it is the ecu but with 2 spares it is unlikely
