I had starting problems with mine awhile ago. Changed injectors and crossover tubes which fixed mine. Engine starts better, runs nicer and quieter than it ever did. There are also other things that could be your problem. There are some threads about this. try a search and see what you come up with. In my case I took it to a "good" diesel shop, not a dealer.
