Please can someone help........... I have a Peugeot Expert 2.0 HDI 2009 very clean and tidy van, been very reliable until recently. Used for work, parked up at property, went to go home, wouldn't run. The van started up, then cut out. Would turn-over but not fire up. Recovery chap came, said it was electrical. Took to garage, they couldn't diagnose the problem, they thought maybe immobiliser? Went to electrical specialist (did all their checks) they can not find the problem and think it's fuel. We are 4 weeks in and getting beyond frustrated. The electrical garage said they believe it is a fuel problem, a small leak in fuel system so pressure reduces overnight (or if left for a long time) they used 'easy start' and it would fire up and run but when left for while it would only turn over and then stop. Does any one have any experience with this issue. Any guidance at all would be greatly received.
Thank you. DB

Easy start. Ugh. Use the priming bulb to remove air from fuel system before trying to start. If it starts it points to fuel issue.

If it eventually runs after easy start then it’s not immobiliser or electronics: they would just prevent it starting no matter what.

Ideally you need to get diagnostics on it too: start reading data off it to see whether there is a fuel pressure issue or other things

As above, you need the proper diagnostic tool 'Diagbox'. Not too expensive to get one on eBay or there are specialist sellers too.

They need to look at live data it could be a failing starter so not cranking fast enough when cold or a failing injector is leaking off fuel keeping the fuel pressure to low to start (around 250 Bar is needed before ECU will trigger injectors)
