A buddy of mine gave me his 300d that had been using since he could not take it with him since he was moving. He told me it was driving fine and then one day would not start. It sat for about 3 months and I just put a brand new battery in it. The car cranks but does not start. It does sputter out smoke from the muffler when I am trying to crank it and the glow plugs come on and shut off when I turn they key. I have tried to start it in Park and Neutral with the same result can anyone help me out. My buddy said some guy who own a junk yard told him that he has a rebuilt engine and that he should just replace the engine. I just think he is trying to make the sale.
