John Deere 244 J 2.4

I have a 244J John Deere around 2000. got on it one day and give it gas and between 500 and 1000 rpm it would jump or hesitate, at full throttle ran fine, fuel pump had a small leak, next day would not start, so I put a new fuel pump on, and turns over no start, I ordered a Technical Manual from JD and the best part is it does not have anything to do with the motor, so i am ordering that manual, 300$ for both better than spending money guessing. thanks for your help,
also it will thy to start with start spray but will die,:Banghead
