The engine fires after 2 or 3 times?


Translated to English via Google Translate...
My mileage is 300,000 km. For a month, the car fires 2 or 3 times. It is always like this when I have a stop. For example at night. All day later, start the car once. No problems. I will add that I have gas installations. LPG. I checked the LPG emergency fire and it ignites. Unfortunately, not on gasoline the first time. Would the fuel pump be bad
