Put new flywheel conversion kit in it and it drove fine. Drove it to store put 70$ in diesel and headed home. On way home when i slowed down for car it blew out a puff of white smoke and the temp gauge went way up so i shut it off. Now wont crank over. It was running fine.is my motor shot? Someone said an injector couldve gotten stuck. Im tryin to get glow plugs out now for some reason, boyfriends workin on it. Im helping. Lol and cant get to first or last one on passenger side. Any suggestions? Got rest of them through fender well but this ones hard get to. Something about trying to crank it over and see if fuel comes out. Can someone suggest how get glow plug out or how do i kno if its shot? Does anyone kno what im saying? Help. Lol
