Jumper 2.2hdi hard starting in the morning

[Kandilx]

Hi i have a 2008 citroen jumper with 2.2 puma engine that have a problem with starting after long colder nights engine was recently rebuild and i did check the injectors also
The engine take about 4 or 5 attempts before finally catching up and if i stop the starter right away it dies immediately, i have to wair 2 or 3 seconds once i get the gas pedal to respond engine doesnt stall anymore and after first start it starts everytime
I did check the rpm while cranking using alfaobd and its 400+ rpm
Fuel rail pressure is around 250 to 350 bar
I did change crankshaft sensor and scv
I did blank the egr as it was leaking while closed
Ambient temperature is 15 to 20C so i guess glow plug are not a suspect here
Currently i suspect air in fuel rail or wiring of the crankshaft senor
I am not sure how to check both
I also suspect injectors when they are cold
Any ideas or guidance for this problem?!
Below is a video of the problem

Try using the fuel filter hand pump a few times before starting to see if this helps.

This model doesn't have a fuel handpump

Well an air lock in the high pressure lines could be it, still after that many start attempts I think it would be purged.

My money is either on:
Bad electrical connection to one/more injectors (maybe shorted/damaged wires).
Leak in the high pressure fuel lines either to the common rail, or from the rail to injectors.
You may also want to check around injectors that you don't have any cylinder blowby - not likely but worth checking.

If you want to ensure the high pressure lines are bled properly just disconnect electrical connectors to all 4 and crank the engine for some 10 seconds.
By then any trapped air should be bled out though the return lines, refit connectors again and see if it'll start.
