Hi, my name is***** will be assisting you.

Try running the machine with the fuel cap loose or off. There is a vent in the cap on the majority of these machines, if this vent becomes stopped up it will not allow for the tank to vent properly which will cause a vacuum inside the fuel tank and fuel can't flow out of the tank even with a fuel pump in the system.
