Greetings. I’m new here and I’m asking you for help. I used the search function and so far did not find a problem that really coincides with mine. I’ve been picking up my ZX for a month now and I picked up the part from Austria. On the trip I didn’t notice any problems, however, when then 2 weeks later the tank needle tilted over half to a quarter it started with the problems. Again and again I had the problem that while driving a n power failure up to 0, which I got control of at the beginning by “pumping” with the accelerator pedal again and thus I got back my power. Unfortunately, these dropouts took to the less I had in the tank. Up to now the car could drive at most until the reserve light started. During the drive to the petrol station about 3km I had to stop 5 times, because the “pump” did not work anymore and the engine simply went out while driving. And the car jumped up again immediately and had full speed. So it was noticeable that the problem only occurred in gears 4 and 5 mainly. So now at the petrol station fully fueled and see there, the power is back again. Unfortunately it then started again after reaching half of the fuel level with the power loss. I have now replaced the fuel filter (no change) , checked the air filter and the petrol pump once looked at. Contacts and everything still sees On the advice of a buddy I also drilled a small hole in the tank lid to guarantee the tank ventilation and ventilation. In the tank is also enough The car also has only 60,000 down and is in itself in a well-kept condition. I wonder what can cause this power loss. The petrol pump is just my greatest attention, and I wonder to what extent the pump can have to do with the fuel level. I just don’t understand the interplay of level, 4th and 5th gear while accelerating and loss of power.
