Alright so, I bought a ke70 probably about a month ago, and ever since I've been having problems with it. Occasionally all the charge will drop from the battery, at seemingly random moments. It will start fine, then a hour later, it won't. I was stuck with this last night, and a passer-by gave me a jump, but it just kept turning over and not starting. He remarked that it could be the fuel pump. I don't have much knowledge of cars, just trying to learn a bit about them. I turned it over probably like 10 times at varying intervals and it started to catch and finally started. sometimes it will also start, but will jolt and cut out.
Don't hesitate to ask if something doesn't make sense in the post, i wrote it quickly.
Thanks
