I have 1998 Accord EX 5 speed with 306K miles. It was working great but just yesterday (8/22/14) and won't start-up anymore. I got a jump from the neighbor and drove to Discount Auto parts so they could test the battery, alternator & Starter and all the test results were Excellent!

I'm confused as to what could be the problem. Is it something I could fix on my own?

Any and all suggestions would be appreciated!

Thanks.

Since it started and ran okay to Advance Auto Parts, with the help of a jump, the problem must be battery-related. Try cleaning the battery terminals and cable connections. I would also remove and fully charge the battery, which most auto parts stores will do for free. My gut is that you need a new battery. If you end up buying a new battery, get them to charge it prior to installation; otherwise, it could damage your alternator. Alternators are battery maintainers, not chargers.
