hi, i have a peugeot 307 2.0 hdi 90
it comes up with anti polution fault and eml
it will start up but soon as you put your foot down it will die and not restart.
took it to a garage and they put it on a diagnostic machine which gave me back two fuel pressure faults.
they have changed the fuel filters,flushed the lines, changed in tank pump, changed two injectors that were leaking and still it is doing the same thing.
do you have any ideas on what this could be?
thanks
