I have a Valtra 700 that will start and run about 5 seconds then goes dead .The first time it did it I sprayed starting fluid in it and it started right up and ran fine after that,it has sit for two weeks and i went out today and it did the same thing started right up and ran for 5 seconds and then went dead like it ran out of fuel.I tried to start it again and it would turn over fine but would not start ,I guess it's not getting any fuel any help would be great thanks, Geter
