how much fuel is in the tank ?
i've seen RV's where one of the fuel pickups broke (usually for the generator)
and the genset fuel line was spliced to the rv fuel line
NO problem as long as the owner remembered to not burn all the fuel using the genset
if the gas gauge shows low, i would get a ride to get station and get 5 or 10 gallons to pour in the tank
got emg road service, they deliver gas (5 gal), just pay for the gas, it won't come from a discount station, but probably your least expensive option at the moment
IF it is a low fuel problem
and don't forget the ignition system
weak spark can cause problems
