i have a 95 bronco 302 and having problems starting and shuts off while running. I've changed/inspected most of the starting system and was wondering if anybody has a diagram or could tell me where the grounds are located?
Battery ground goes from the Battery (-) to the passenger side front of block, from there to frame. The other engine ground is from the rear driver side of the intake to The fire wall, (braided strap or a number wire).
Here are some pics & diagrams, diff years & engine type in some, but all are same as your 95. I've been collectng em for awhile and figured now is da time to post em up and add/change em as I get my eyes coordinated w/my brain. I may have mixed some up such as in instr panel showing "upper ground" confused w/"lower ground"
Engine Block pic in a 94 5.8; "...The black battery wire goes from the front bolt of the engine mount (on the block) to this tab & up to the battery post, where a smaller black wire goes to the core support, providing a continuous ground path between the engine, frame, battery, & body..."

Frame & Battery pic in a 93; "...With the wheelwell gone, it's easy to inspect the frame ground, just inboard of the spring tower on top of the frame rail. The battery ground cable is stripped ~3/4" and a tab is soldered on so it can be bolted to the frame..."
