Troubles starting.

[Descabarian]

On initial start when motor is cold. The engine will start immediately than shut off shortly after. It is as if it is not recieving fuel? Just cuts out. To start I have to hold the ignition and press on the gas pedal for a good 15 to 25 seconds. When it starts it blows heavy black smoke. Any ideas? I have changed the glow plugs. No changes.

Ok. I learned through my own research that while it sits it looses its prime. Does anybody know of a quick and cheap fix?

change fuel pump and check for leaks. all it takes is just a little leak that sucks air in and will shut it down.
