Ok, so it sounds like you’re fighting two fronts. The charging was definitely an issue since you were able to start it repeatedly on the charger. Now I’d start working to determine if you’ve got air in the system. As 5150 said, "you can also insert clear fuel line on the return line to see if you have air bubbles in the return fuel."
