Hey everyone I'm going out of my mind . Well I posted before about starter headaches In my 08 f150 4.2. Well after a couple days of checking everything a friend suggested to see if the engine sized . so I grab on tight and turned the engine about a inch figured ok its good then I went to turn the fly wheel with a long screw diver and notta couldn't move it at all . So is it possible that the fly wheel is stuck and not the engine ? Any help would be greatly appreciated . Thanks BillyBob1
