2002 dodge diesel hard to start

[Doumecq]

When trying to start it the starter turns fast then almost stops then fast again. This happens whether the engine is hot or cold ( kind of like a gas engine with the timing set to far advanced). When it starts it blows a lot of black smoke.
Checked batteries, cables and starter all in good shape.
A friend said it could be one or more injectors leaking but I started it let it run for five minuets then shut it off and restarted it engines kicks back the same as if cold

Hi Doumecq

Hard to say for sure what the problem is, it could be a lot of things. This is the order I would check things in:

-Make sure the fuel filter is clean.
-Make sure you have good lift pump pressure.
-Park the truck in a steep nose-down attitude. If the problem goes away, you've got a fuel drain-back problem, air is entering the system when the truck sits.
-Have the truck scanned while cranking to make sure it's seeing a good crank signal etc.
-Pull the injectors & have them bench-tested. You can ship them to us to check them or I might be able to find someone local who could do that.

Hope this helps, let me know if you need anything else.
