Hello, My uncle’s car has the following problem ONLY in cold condition: It starts immediately, runs about 1 min, then suddenly runs out. Now you have to have long organs, until it starts a bit bumpy, then it runs the rest of the day without problems and pulls also quite normal. But if it stands again until it is really 100% cold, the same problem. The car was in the workshop, there it was found that the pressure sensor in the rail tube is allegedly broken. The sensor cannot be replaced individually. In addition, if you change the tube and sensor after a short time the pump would always be defective. But if you wait about 10 s after the perfect start, until the oil pressure is almost full and immediately brings the engine to approx. 2000 revolutions and stops, then after approx. 60s it starts to rumble and rattle and runs only on 2-3 paws. If you keep the notor running over the speed and can survive a few seconds, it will run as usual. If the jamming light has come, then turn it off once again, start again and start off. The problem will not occur again until the next long standstill. The downtime must be longer than 8 hours. Now the questions: 1. Can this really be on the sensor? Why should it go out if the sensor reports that k a pressure is there, but this is really a problem? 2. Why doesn’t he do this at the second start, which is still not nearly warm? So this has nothing to do with temperature, but with service life. 3. does someone know exactly the solution for this problem? 4. does it seem to actually fall the rail pressure after about 1 min, so no sensor error, but a fault of the pump? In any case, I don’t think it makes sense to replace the rail tube with sensor, since the pressure j a apparently actually falls and only stays running at high speed. But why does this fall once after a long downtime and then not again?
