Chrysler 300c 3.0 crdi Cold start improve

[bugarcek]

Hi

This car starts perfectly when warm and after 5-6 hours again problem.... You have to crank long time... I think fuel is the problem.
Glow plugs are new and they work okay. I check fuel pipes, but I can not find the problem, fuel fitler is new... There is no any light or dtc on car...

So here I attach file if someone can make any mod for better cold start.

check fuel pressure, you have injector faulty or a high press fuel pump that don't reach the fuel target
