RENAULT MODUS 1.5 dCi Delphi - Does not start with a warm engine - no pressure

Hello, I have a problem with the above-mentioned model.

When the car is cold, it burns nicely, when it is warm it does not want to start or it starts very hard when it starts, it goes.

CLIP shows a problem with the pressure on the rail, the overflow test indicates injection number 2, funnels number 3, rather to be replaced.

I also suspected damage to the pump. External service got into the fuel filter and drained the fuel, here's what was inside:


I am thinking of replacing the pump itself with a new or used one, but not caring, and the second injection itself. Does such a replacement without cleaning the system make sense? The service says that without cleaning I will get the injectors.

PS: Injection 1 is new because it was replaced with a used one, so unsure so without performing overflow tests, I replaced it with a new one.

If there are filings in the fuel system, the pump should be replaced, probably the spider with the valve, the pipes and the cleaning tank, all injections on the table are open, cleaned, you know the filter - after the repair, you often drain the fuel from the filter into the black bottle and control it, it will not hurt to look into the tank somehow the time is dark there and you can see the lantern well - generally a strong magnet and drive around the bottom of the tank and check what will stick. Generally, the topic to be covered, but also the possibility of an entertainment Monday - very expensive. Greetings.
