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

Problem solved. I replaced the entire pump complex. I don't know if it's the fault of the fuel pressure regulator or the pump itself. The pump fit Mazda 6 2.5 v6. I only changed the power plug, the engine fires in 1 time. Thank you for your help.
