Failed injector. Its a shame they didn't say what feature of the injector was not performing correctly.micheldeman wrote:I have taken out the injector and brought it for a test, which failed they said.
Leaky injector seals don't usually inhibit starting, they make a bit of a mess and sound bad. You may also be down on power a bit.micheldeman wrote:My reasoning is that the engine was running before and not too bad either. It always started immediately, it was just that the injector seal was leaking and needed replacement.

If the injector has failed the test for leakoff then the pump will never be able to pressurise the common rail very much because its all returning to the tank.micheldeman wrote:If my reader is correct in saying that the high pressure pump is only producing 8bar, then there's something wrong with the HPP, but I have never touch that pump, so might air still be the problem?
I captured the cranking pressure on a Lexia system connected to a 1.4 HDi 16v (Delphi system) which would be similar to yours.
The image is the trace from the video of live data during the two engine cranking cycles (engine doesn't fire).
The video shows 2 cranking cycles with a gap between. The engine never fired.
