engine stops

[alph0nse]

Hello everybody. I have a Mercedes Vito 108 cdi from 2003. When it is cold, runs ok. When hot, in takeovers or on hills, the engine stops and the edc light is on. On the tester it says "1187 fuel rail pressure inspection".
I went on Mercs and they say: change injectors. I changed the injectors, spent lots of money, but no change. I put the tester on the road, the pressure is about 1300 bars. I put also a new fuel pressure regulator, no change.
What else could be ? Please help me before I burn it.

Has the fuel filter been changed latley?

I change the fuel filter when I change the oil (2 weeks ago), but this problem is dated 1 year. Thanks for reply

It could be a fuel pressure sensor issue or high pressure pump problem

Problem solved. It was the high pressure pump. I put a new one by myself, 2 hours of work. Thanks everybody !
