I've checked for spark I checked the fuel injector cleaned it with the blowing through it with the starter fluid and it's getting power to the fuel injector I think it could be the fuel pump. When I take the line off there's never fuel by the injector..my question I guess is can you put an inline fuel pump with the fuel pump that's in the tank, when I take the line off, fuel does come out. I don't have a way to check the pressure.I just purchased a second hand and it hasn't been started in 2 years because he said he couldn't get it started either.
