Having some issues here. 94 250 non turbo 7.3. 191000 miles. Recently purchased. Have reasonable knowledge of the diesel family and its history of glow plug/controller problems. The truck has started difficult while the engine was warm since I bought it. Actually, I have to dump a little fuel into the intake in order to start it. *This is problem 1* Second, today, I went to start it and it didn't even fire. It was cold here in NY, and the glow plug controller just clicks on/off every second. Probably have a few bad GP's but that shouldn't keep it from starting. I have installed a controller bypass switch and am manually lighting the plugs in leiu of the controller issue, but the darn girl still wont fire. Any suggestions?
