Glow plug

[Alkhodre]

hi all. I have an Volkswagen transporter .
problem number 1 is diagnosis number : Cylinder 3 Glow Plug Circuit P067300
After I changed this, the car wouldn't start.
New diagnosis said: Cylinder 2 Glow Plug Circuit P067200
and : Cylinder 4 Glow Plug Circuit P067400.
Car doesn't start.. Anyone?
Grateful for help

Crank no start?

No crank?

Will it start with easy start?

Fuel issue after removing the fuel rail?

Van spec,? Year? Engine?

More info please.

Plug 3 is often the expensive pressure sensor glow plug. From which end of the engine did you count from?

 

[Alkhodre]

crank, no start.
car starts with easy start. When easy start stops, the car also stops.
This issue came after I removed diesel -pipe system.
Before this the car was starting without any problem.
2.0 l engine. 2021 model.

So a fuel issue. Air in the system.

You will need to bleed the air out from the hpfp, the rail, and hard lines to the injectors.....

And check all the injectors connectors are all plugged in properly .

You can prime with the lift pump with a scan tool. (,IE vcds)

Why was the the pipe system removed in the first place?

That’s the VW theory but haven’t there been so many cases where it just doesn’t work and conventional HP line bleeding was required in order to get the engine to run.

Yep... They can be a nightmare when run out of fuel.(VW say about running the prime pumps for 3mins each for three times - before cranking)...

Let alone opening up the high pressure side....and the hpfp is prone to failing if run dry for even a short time.

For this one I'd be looking at the rail pressure while cracking. . to see if pressure is building.

Id imagine there is air in the system still.....I was under the impression that the injectors can't fire unless they had fuel in them, as the squishy air can't be pressurised high enough to force the spring back.

thank you very much for your good advice.

Was the air bled from the system before any cranking (by VW procedure using lift pump)?
