It is my understanding that the fuel lft pump has been replaced( updated) and is now gone back to the old way and is re installed in the tank.
I have had to put 3 lift pumps in since new, little did I know but Cummins tells me that the lift pump delivers minimal pressure and shortens the life of your injector pump.
So if that is true perhaps it is best to eliminate the lift pump and go with the new in tank pump. I plan on doing it the next time I have a problem.

Check the fuel pressure at the filter. Odds are the lift pump, located below the filter, is toast. Continual cranking of the motor with a bad LP wil cause the injector pump to heat up and burn out. Replace the LP and fuel filter. Bleed the system by cracking the inlet to the injector pump and bumping the enigine over so the LP will run. Once you have fuel at the injector pump, crack injectors 1,3,and 4. Crank the motor for no more 6 or 7 seconds at a time until it turns over. Give the pump time to cool for a couple of mintues between cranks. This process is easier with two people, one to crank and the other to watch for fuel and tighten the injectors once it starts. If the injector pump is fried at this point from cranking with no fuel, the motor should idle, but will stumble all over itself when the throttle is applied.

SOURCE: 99 ram diesel wont start
Did you check to see if there is power to the glow plugs if not then that may be the problem and if there is power when you cycle the key not to start but for the plugs to warm up you may have a bad glow plugs.

Diesel engines fire on compression alone (usually 400psi).The Truck may have air trapped in the fuel system.When you perform any fuel system repair on a diesel it is going to take alot of cranking to get the air out. You can take the breather loose and shoot a VERY small amount of starter fluid in the intake and it should start. Do not use starting fluid much as it can damage the engine. Good Luck.

you'll notice on your valve cover gasket there is two connectors.. the one up front is your 1-3 the one in the rear is your 4-6... you can remove your valve cover and check the connections from the injector connectors to the
connectors on the valve cover.. check for an open.. however you could also have a fault internally in 1 of your injectors in that bank as well.. hope this info helped..
