Not easy for me to explain in English but I need your help.
My car : 2004 narrow body, 1.6 K engine.
During track days (tyres=048, quite a lot of grip), when my fuel tank has less than the half (else no problem), in right turning curves taken in 2nd and 3rd gear, the engine does not receive fuel during a very short period of time and then, when the car is slow (I assume less G force), the fuel comes back to the engine.
So the problem should be around the fuel pump, but what do I need to check?
