Two new fuel pumps put on neither pump will pump system up to prime injected pump
I'm not familiar with that particular vehicle, but most diesel systems have a primer under the hood. You will need to pump that slowly until you feel some resistance. That will push fuel to the engine. The other pump may not be able to push fuel through until the system is primed.
If that doesn't get you running I would suspect a clogged fuel filter. Most Dodge vehicles have one on the frame. Just follow the fuel lines until you find it. There may also be one attached to the pump primer.
Changing that filter would my next action. Whether the pump is in the tank or added on outside the tank, you may still need to prime the system after the filter is replaced. Air in the line may cause it to stall, just reprime and start again.
Good luck.

This usually happens when the lift pump gets worn and fuel pressure drops below 7lbs and the injection pump has to work harder by pulling in the fuel and will destroy the pump,your is probably a vp44 fuel injection pump it needs replaced and they are expensive 1200.00+ but also change the lift pump or change to a fass fuel system,if the lift pump went out and you replace the injection pump it will ruin it in a short time.
The injection pump is not an easy job to change or for a novice mechanic as it has to be set in time with the engine at top dead center,and then the whole fuel system needs to be bleed of air.
