Why does Peugeot 205 diesel engine run on when ignition turned off?
you need to replace the stop solenoid on the top of the fuel
pump if it is a lucas pump. I had the same problem, but they are
are fantastic price, ie £72 plus vat from main dealer, so shop
around or get one from a breakers. mine started without having to
bleed the system, but you might have to. do it quick and it should
be ok, be careful not to get the threads crossed it is fiddly.
