i just purchased a 2007 7510hst i put 3 hours on it in the last few days and love it.i shut it of the other day for lunch and bumped the lever for the mower and it would not start . after checking all of the saftey switches i found that the problem was the lever position.now it cranks but will not start.i started checking the fuel system i have fuel coming out of the fuel pump ,but no fuel to injectors. i do not know much about this tractor any help would be great.
