i have a 2001 cummins and the damn thing well be going along fine and then all of the sudden the thing will act like its lossing power then and slowy keep fadeing away then it will just return to normal like nothing happened , its had prior tranny issues and is that whats causeing this

might be your lift pump, have you checked fuel pressure? been to www.dieseltruckresource.com ? they have a wealth of info if you don't know about it yet.

Yes, check the fuel pressure. If you drive it long enough with a dead lift pump it will kill the injection pump. I think that you can do a quick read of codes by cycling your key 3 times fairly quickly (on-off-on-off-on) and see if a code shows up on the odometer. If just the miles show up I would get the truck scanned. If code P0216 shows up then plan on buying an injection pump or being stranded when it completely dies.

Fuel filter

ok so i thought of the fuel filter and changed that and that didnt help , checks codes and it came up with p1693 and p0216 so since the truck only had 87000 on it its at the dealer getting a new injection pump and lift pump , love the warranty

Since it has the Cummins ECM for the engine and the Dodge PCM for the truck and transmission there are 2 control units. When one has a code for whatever reason it sets the P1693 in the other one to remind whoever checks that they should look in that one, too. Once the second one has the 1693 then the first control unit sees that there is a code in the second and it gets the 1693 code as well. Hopefully they will look in the (Dodge) PCM and make sure that there is only the 1693 code in there.

P0216 is generally the injection pump death code.

You should consider a fuel pressure gauge or low pressure warning light to make sure that the new lift pump is working. The next time it goes out it will probably be on you ($$$$$), it would be good to have some warning.

My buddies 02 just did the same thing - lift pump died and took the injector pump with it. The dealer put a intank pump in it and injector pump - it runs great now - warrenties rock :D :D

1693 = engine computer trouble code 0216 is an injection timing event failure

the symtoms you are describing are common to injection pump failure as a direct result of low lift pump pressure starving the injection pump for fuel (which is what cools the injection pump) and thus causes it to fail. The stock Carter lift pump has been problematic for this application. apparently carter says that Dodge is stretching the limits of the eletric pump to be able to pull the fuel from the tank and then push it to the injection pump. There are several options for repairing this. Dodge has gone the route of a newq in-tank pump and eliminated the side engine mounted unit, so far a decent solution though guys with minor chips have noted that they are still drawing down the pump pressure at WOT and even at idle the pump has a low pressure. FASS is another solution is a Fuel air seperation system, rather large with filters that mounts under the cab to the side of your frame. This setup has had good results, thought it is rather large. there is also the RASP system, which is a belt driven pump that mounts under the front of your engine, keeps the stock carter for primin ghte system and then switches over to a mechanical belt driven pump once the motor fires up. Then finally and most recent was the development of a performance cam shaft (as the stock camshaft does not have a lobe or eccentric for driving a mechanical lift pump) and mechanical lift pump that use a cummins lift pump similar to that used in the old 12v's. They are having great results with this and what is really cool is that recently one of thier test combos reached 400hp with a stock turbo, mild injectors and this camshaft with no egt issues.

Nothings cheap but the key is getting a fuel pressure gauge on there next time and keeping the pressure and flow above 10psi even at WOT but not over pressurizing the system either

good luck sorry to hear about your misfortune. Replacing a VP44 though is a fairly straight forward process, not like a p7100 in a 12v which is heavy and fights you timing it.
