what cummins diesel engine model is in the dodge
cummins make a large range of engines all of which have various pump pressures depending on the injector set up
ask your question again and concentrate on the engine details
Most likely you just have air in the lines.Crack them open one at a time and bleed them with the fuel pump off and on till you get fuel.If it fires dont hit the throttle let it sit and idle and close the line.Does it fire up with a small whif of starting fluid?
drain the fuel, change the filter, add fresh diesel. cycle the key several times and see if she fires up. you might have to crack the injector lines to help in bleeding the air out of the system. the good thing is the vp44 injection pump doesn't know what its pumping and 2001 24v cummins do not have electronic injectors, so you should be ok.
if you have a Cummins diesel then it probably has a geardriven water pump. Dodge gas engines have a belt driven water pump, much cheaper. Check around for a re-man water pump if you have a Cummins installed. The prices vary enormously.
On a cummins turbo diesel the water pump replacement is quite simple i do believe. just have to remove the belt. The clutch fan, and pulley, then the water pump is right there i believe being held on by 4 bolts only and remove. Remember to place the wate pump o-ring on the water pump and hold in place with sort of adhesive just to make sure it doesn't slip out during installation or this will cause a leak. Once everything is installed then you will need to purge the cooling system of the air bubbles by letting it run and watching when the thermostat opens up. You can tell because the level will drop in the rad or over bottle, depending on what controls the fluid. Let it open two or three times, and go for test drive, all should be well...hope this helps
Please clarify the "loosing power" does it lose power and shut down or does it loose power but will idle? Your Cummins is electronically controlled so oil condition is important, fuel leaks, oil leaks, leaks in the air ducting between the turbo and the intake, sensors, water in the fuel. Do you get an engine light when this trouble happens? Dodge uses a lift pump to carry fuel to the the injection pump, is it working?
any of the non computerized aka 12 valve cummins will interchange going from the p7100 pump on the 94 to the ve injection pump on the 92 may mean rerouting some of the fuel lines to hook it up. make sure you use all the sensors from the 94 engine though so all your gauges read correctly other than the fuel system the engines are identical though so should have no issues doing this
