I am having intermittent starting trouble with my jeep for some time now. I have ran down all of the know problems (I.E. Factory battery, WMU Unit, Neutral Safety Module) the last time it happened instead of jumping it, I jumped the ground only and the truck started. I have read all of the intermittent starting threads on the site and now believe that I have to change or add another ground strap. I have 2 questions, (1st) I broke the hood ground some time ago, and grounded it directly to the battery since it no longer reached the hood, could this be the problem? What is that ground strap for? I see that it attached to the firewall first, before it went up to the hood? (2nd) where is the main factory ground, I would like to follow it and see if there is any corrosion, or breaks etc, I spend a lot of time the beach and winter road salt conditions, so maybe im loosing factory ground, IDK?
