When you are cranking my 97 gmc diesel when it cranks you try to give it a little gas but it like it has no affect it cut off and then it want crank for days what is that called?
could be one of two problems, when starting a diesel or any
injected motor you never touch the gas pedal or you might flood the
engine, the glow plugs may be weak and added fuel just renders them
useless, otherwise you might have a bad fuel filter or pump.
