Cummins loosing power - stalling

Have a problem with my 2500 Cummins, it looses power especially when cold. If engine is switched off and on again immediately it goes okay for 10 to 30 secs maybe, but then again looses power. After a varm up period it still behaves peculiar, but usually will regain power if pedal is released and pressed again. No error code returned when hooked up with analyser. Could it be TPS or has someone come across this ?

Not sure, it could be the TPS or computer. Does the truck do ok once it's warmed up?

Those guys are hot on the Cummins diesel.

It still behaves peculiar after warm up, but if pedal is released and then preesed again it will regain. This does not work when cold. As I´m owerseas could you help with a name or two where I might source for TPS. Is there any way to check out the TPS ?

There are several discussions about TPS for gas engines in this forum, so I'd start there. The folks at TDR can probably help a bunch, too. sorry I don't have any better info.....

Just had the same thing with mine. I looked all over the net and couldn't find anything and now that I got it fixed I figured I'd post the problem and solution for the next frustrated Ram owner.......Fuel injector pump!
Don't let them give change the fuel filter ($190.00) and bleed the lines ($140.00)following the diagnostic procedure crap. The good news was after spending a month frustrated it was covered under warrantee!

To me it sounds like the engine is derating. The reason I think that it is doing this is because when you shut the key off and turn it back on it overrides the shutdown surcit. It is posible that it is the tps but usaully those go out they won't work at all. Take it back and tell them to monitor the system when they do the scan. It might be lots of things

I will tell you that it is probably the lift pump. That will fail first but your truck will still run until it burns out your injection pump.( Bosch supplies the pumps to these trucks) They will replace both pumps plus your filter because thats the way they do it. In Canada at a dealer it could cost you up to $5800 or $3800 from an independant shop. Unless you catch the problem before it damages your injection pump which is almost impossible. There are no codes for the lift pump.
Your symptoms would be
1. Starts and idles fine but if you haven't warmed it up good, it will be super sluggish with no power and then it will suddenly come to life.
2. You might find that once warmed up, at around 80 to 90 kms or 45 to 55mph it will hit a sort of no response zone. Pedal to the floor to grab the passing gear and then back off to resume. It doesn't seem to happen once you get above the 60mph but in time it will.
3. It seems to be a little louder than normal.
4. It might also seem to not run as smooth as you remember.
5. The truck most likely will have between 95000kms/55000miles to 160000kms/90000miles on it. if this is the case...
Please be warned. The lift pump failure will inevitibly cause your injection pump to burn out. There will be the forementioned signs that seem to last for ever and you adjust to the problem and learn to drive it that way. This could cost you your life. One day you will attempt a pass on the highway or a turn at a light and you will lose all power. There will be no warning, no dashboard notification or alerts. This situation almost cost me and a few other people their lives. As these trucks get older and more of them reach this point on the odometer this problem will become more reaccuring.
I am in the begining stages of legal action to try to get Dodge to recall these trucks with this set up. Mainly in the 2001 and 2002, 2500/3500 Cummins Powered Trucks before people start to get hurt or killed. I have the backing of numerous Deisel mechanics who see this problem escalading. Cummins blames Dodge, Dodge blames Bosch and Bosch blames them back. This is a problem that must be addressed by Dodge. It is their trucks and their customers that are at risk. If you are aware of anyone that has had an accident or a close call because of this, e-mail me at [email protected] and I will supply you with an address to send your statement of concern. In the end a recall will reimburse any monies put out as a result of this problem plus address the safety concerns and hopefully prevent imminent tragedy.

Withmyeyeswideopen ,
I don't know for sure if my situtation is the same as yours but this is what is happening to me:
I was driving in heavy traffic and all of a sudden my truck (1999 Dodge 2500 Quad Cab 4x4 Long Bed w/ Cummins Turbo Diesel) just shut off! I lost all brakes and power steering and coasted to a stop in the middle of three lanes of traffic doing approximately 45-50 mph. I hit the flashers and put the truck in park. My check engine light came on and it restarted immediately. About five minutes later, while trying to limp home, the tachometer suddenly dropped to zero but the truck kept running and a few seconds later the tach started working again. I made it home and later that afternoon started the truck to go to Autozone and have the fault codes read and everything was fine. No check engine light, tach was fine, and no stalling. This morning on the way into work..the tachometer suddenly dropped to zero, the truck kept running, the check engine light came on, and a few seconds later the tach started working again.

The injection pumps in the cummins engines are prone to going bad I don`t know about the newer ones but where I work we`re constantly replacing them. I`d advise to replace the filters often, after we started changing them at every oil change the problems slowed down
