    Next time dont use eather and pump the primer valve for fuel system until it's hard and try starting. If it starts easier you have a leak in the fuel system and your loosing the prime overnight. A hole in the return line or supply line, loose fuel filter, loose hose clamp. You wont see a viable leak

    i do pump the primer valve and i could hear the return NVR open from pressure still not working i also check the fuel pipes and release the air but no air was inside

    Does the primer get hard? You have to pump it 50+ times to over come a potential leak. How many hours on the machine. Some systems have check valves that go bad in the fuel system. What's the serial number

    the primer get hard in about 5 times but not very hard as the NVR openes Model / Type :ZX 470 LCH - 3F IDENTIFICATION NUMBER : *HCM4 XM00V00024623*
