ducato non start

i have a 53 plate ducato which cut out whilst driving the AA man said crank sensor so i replaced but still non start .
i get number 1 and 4 injectors pulsing whilst cranking but 2 and 3 i get no pulse i have checked continuity between the ecu and injectors 2 and 3 which is ok live and earth,
does this mean my ecu is knackered or has anyone any ideas
the AA man plugged in again after the crank sensor had been fitted but he said no faults were showing .
thx all
Gary

Re: ducato non start

if 1 & 4 were down you would get unburnt fuel (from 2 & 3), I would get fuel pressures checked first.
