Good morning,
I have a Peugeot Expert III of the year 2008 with a 1.6 HDI 9hh engine.
We have proven that the wiring from the switchboard to the pressure sensor is not bad (it has continuity). The high pressure pump has also been proven that it is fine.
But what does not fit me is that after disassembling the pump and reassembling it with the open door it started perfectly, and then when closing it it stopped and did not start again.
On the other hand, looking at the tensions that reach the Rail pressure sensor, the mass pin is only activated when the door is open on some occasions, and less and less. As if the switchboard woke up only when the door is open, and not always
thank you very much for your attention.
Greetings.
