    Jeep won't start

    About a week ago I go to start my jeep and it won't start. For about a fraction of a second it makes a sound then nothing. No clicking. No dash light, absolutely nothing.

    I checked a few fuses, "starter fuse" and didn't find anything. So I jumped it and it ran fine for a few days with no issues. Then this morning and again this afternoon, same exact thing. Don't know what to do.

    The only thing that seems a bit out of ordinary was my "sway bar" light has come on while highway driving a few times. I installed a new battery about 8 months ago.

    If anyone has any ideas would appreciate it.

    Could be an amperage draw, alternator failure or a bad battery.
    Have you added any aftermarket electrical devices lately ?

    Sounds like a bad battery cell. Have it load tested!

    Maybe your local auto parts store will check it for you. They usually do it for free.

    Check for clean and tight terminals. Specifically look for heavy corrosion on the cables.

    Yea I guess that's next. I just checked alternator by disconnected neg battery while running and there was no change.

    It seems like a connection of some kind is gone bad, like a relay, but would I be able to start it after it's been jumped and turned off if it's a bad relay switch?

    This is not a good idea on newer vehicles the sudden spike in voltage can fry your PCM

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
