Emergency stopping problem, I need help

Good day everyone I bought a car 2 weeks ago and it gave me trouble. I have a stalling problem in my Peugeot 307 1.4 HDI xr 2004 model car. They said it was due to the pressure switch. I bought the car from the expert and they changed the pressure switch because it was not a big deal. The problem was not solved. There is no problem when driving normally. The car stalls only at traffic lights or stop-and-go situations. I turn it off and on again and it continues to work. At the next stop-and-go situation it stalls again in the same way. They said I changed both of them. They said the turbo hose. I changed that too. They said the crank sensor. I changed that too and there is no improvement in the car. The problem continues the same. Fuel filter, oil maintenance and everything was done. The brain says that it makes air that's why it stalls. I go to a pump injector shop. They say it may be an electrical fault and it's not caused by the injector. I go to an electrician and he says it's the injector. I don't know which one to trust and have it done. They don't give me a guarantee that it will be fixed after paying for the injectors. I haven't been able to use the car for 2 weeks. Please help urgently.

I spent a total of 25 thousand TL on the vehicle and it still hasn't been fixed. Could there be another reason for this problem? Could you please help?

Could there be a problem with the timing chain or belt (whichever is present)?

Is that why the vehicle stops during stop-and-go traffic?

[QUOTE=GAMY0106]Does the car stall because of that? [/QUOTE] Mine has been having problems with it for a while, so that's the first thing that came to my mind. I had this kind of stalling problem when I first got the car. The spark plugs and coil were old. There was also a water leak and excessive oil loss. I think the stalling went away after the spark plugs and coil were replaced. I don't remember if the problem was related to the water leak, but I'm writing this for information.

Thank you, all of them were checked and there is no problem. I found someone in Bursa, he looked at the internal engine installation and said don't let anyone else look at it, the problem will definitely be solved. We will have the internal engine installation checked today, let's see.

I think we have the same problem. The stop and oil lights come on when we stop. They say the problem might be the oil pump. I'm thinking of replacing the sensor first. It looks like it'll be a lot of work. I hope the problem is found and resolved soon.

I have a Partner Tepee 1.6 vehicle, the problem is that the vehicle stops while driving, giving a fuel pressure error. We checked the intermittent crank sensor, there is no problem. We had the software and the ECU checked, there is no problem. We changed the fuel filter, the same vehicle stops while driving, it does not start immediately when it stops, it starts when I give diesel with the hand pump, then it stops again. I have not found a solution, I do not know what to do.

Sir, does the car stall while idling or does it stall when you first start up when you give it gas?

Hello brother, I am writing from Ankara. I have a 307 1.4 HDI 2004 car. I had the same problems. I changed everything. The last thing I did was replace the fuel pressure sensor. The system there was rotten because it was close to the engine. It was causing the chassis. When I opened the system that goes to the sensor a little, it became clear. I changed it and the problem is gone. If you want, I can suggest you have it checked.
