The mothers 307 in typical 307 fashion has chosen the best possible time to develop a fuelling issue...
I don't have much time to work on it but I've so far tested for air ingres into the fuel system, doesn't appear to be leaking anywhere.
Next line of enquiry was the high pressure pump.
I don't really know anything about these 1.4 hdi engines as this is the first time in 5 years it's ever gone wrong, but I'm thinking high pressure pump failure giving the same symptoms as a 2l hdi when it goes.
Diagnostics show nothing wrong other than there's no fuel pressure while cranking, so hp pump or fpr?
Do the pumps on these have a pressure regulator similar to a 2l? All I know so far is the pumps a bitch to get to
Any thoughts appreciated
