Hard start when engine is cold
Hello colleagues,
I'll start with the important information first - the car is a Volvo 850 2.4 143 horsepower with gas injection installed.
In the last month there have been problems starting the engine, especially when it is cold (it has been idle for 7-8 hours).
At the same time, we found that there was no fuel in the fuel rail due to a faulty fuel pump, which we successfully replaced and now that the car starts, it is running normally. However, it often takes 6-7 attempts to start the engine.
So far we have replaced as follows:
However, I would like to hear what you think before we do anything.
Thanks!

So far we have replaced as follows:
- Petrol pump
- Intake air sensor
- Fuel pressure sensor in the rail
However, I would like to hear what you think before we do anything.
Thanks!
