HELP! [Re: polar] #1105299 10/23/19 03:47 PM Joined: Feb 2000 Posts: 6,239 Bel Buckle, TN 4x4Wire Trail Leader I would go back to the battery and connections. Clean battery connections and double check/clean the ground binding between frame - chassis - engine. The ground does need a good solid bond free from rust and corrosion. Then, there is the TDC (Top Dead Center) sensor. With the 4.0l engine, that is a common problem.
