Sounds like you didn't bleed it. It's air bound. Loosen one injector line at a time and crank it until the air bubbles stop. Have a helper watch the injectors until straight fuel is coming out with no bubbles. Also, next time you do it fill the fuel filter with diesel. It doesn't allow as much air to be introduced to the system. If there's a lot of air it may be wise to have a charger nearby.
