Technical Punto 1.3 mjet e4 does not start after fuel rail removal

[Thejango]

Hi everyone,
I got 1.3 multijet euro 4 engine punto. It had injector problem which I believe I fixed by changing injectors (installed 4x rebuild injectors). Everything was fine until I noticed it leaks fuel from 3rd connection of fuel rail pipes where bolt hold the pipe connected. I damaged treads and it was leaking from there. I removed fuel rail to fix the tread ,however, after putting back it does not start but just cranks. Could there be air stuck in fuel rail and injectors?

Or a bleed.off

So you dont build rail pressure

bleed off from the 3rd pipe coming out from fuel filter? or somewhere else?
Thank you

Revisit what YOU have disturbed

As it was 'better' before

better

I will work on it first thing in the morning.
one question : when I remove rubber pipe from injectors, fuel comes from rubber pipe when ignition is on. I look at the diagram and see that rubber pipe is return pipe. is this normal? I am worried that I might have connected something but everything seems connected fine.

cycle the ingition on and off a few times, this might make the in tank pump send fuel up the main pump

also, I have tried to start one of these with the air flow meter off, it wouldnt start, connect that back up and it might go

I found the same last summer..

Tinkering the other day..
expecting it to just crank.. it fired..and ran beautifully
:shrug:

So had to shut it off and fit the meter and
Filter
