OK... so yesterday afternoon I take the truck in for an oil change (truck at 22K) and have the leaky coolant hose at the back of the engine replaced. Dealer says that they have to keep truck overnight to fix hose. No biggie...



I told the tech that while he is at it and now had more time... to hook up the Star Scan tool and check and see what is up with the extra white smoke and perceved lack of power again. (Had truck in once before with same problem and they repladced the rail pressure valve at like 15K)



Tech also mentions that he notices some fuel leakage near the CP3.



I get a call this am from the service writer and says that my CP3 is bad and they have to get one out of Denver and they need to keep my truck overnight.



I must suck at the search here... did not find any posts about dead CP3's... just a bunch of lift pumps. At 22K should my CP3 take a dump?? What would cause it to "fail"? I am assuming that since the truck ran OK when I took it in... it is that the CP3 cannot make "high enough pressure"



Will find out more tomorrow I guess...

Im noticing more and more of them. my neighbor has a 04 and it would start hard but eventually started then one day it wouldnt fire at all... . towed to dealer and turns out it was a bad CP3. Thats the last we heard. no reason why or explanation... . the dealer had to send it to Chrysler and that was that.

Mine was replaced at 20000 miles. I took it in for a cel with a cooling fan circuit 1 malfunction. Six days later I get my truck back with a new CP3 and the code was caused by diesel in the connector to the fan clutch harness. Does anyone know the source of the external leak? Just curious about future repairs that will be on my dime.
 
this aint good, got 24k on it... . keep us posted... . "the new ulsd, it will not harm your engine"

yea my a@#$$ it won't... . #@$%!
 
Doesn't the dealer just replace the CP3 even if the FCA is bad on newer trucks? If so then I could see why the CP3 could fail so quickly.



Also, I am sure you will have some failures of the internals of the pump... nothing is perfect.
 
Great comments guys... I will ask the tech if the FCA was leaking or... ... . ?



One thing cool I saw at dealership garage area was a new sprinter van with the engine out... pull the grill and slide it out... real easy lookin to do... beats the old "dog houses".
 
It's looking like the CP3 is the 3rd generation's version of the 2nd generation VP-44... :mad::D



I'm not sure that the three referenced cases in this thread indicates a major issue with CP3s. Considering the number of 3rd Gens out there, if it was a major weakness, I think we would be seeing more than a handfull of reports.



Just my . 02 worth... ... ... ... I just haven't seen many reports of problems. When I had my 97 CTD, I recall reading about numerous VP44 failures.
 
Would a bad FCA cause a fuel leak and still run fine?



LFarmer, an external leak would be a seperate issue.



I was commenting on the original issue of the white smoke/hard start/lack of power, which from past reading one of the first places to start is the FCA on the CP3 for trucks out of warranty.

yes sir it does,what a new CP worth after the warranty is up---new VP44 can be had for around 1100 bucks.



:confused: I think this is rather glib. There have been very few CP-3 failures. Or did you mean the CP-3 is the 3rd gen VP-44 in the sense that they're both injection pumps? :confused:

I think GColeman's right on.

Those were the symptoms as mentioned before... and they are back again. The first time it was the rail pressure valve... they did not say it was or even mention the FCA.



So... what IS the price of a new CP3 from the "dealer"... ha ha ha... or do I NOT want to know? Thank goodness for the warrenty... unless they say the 5inch magnaflow exhaust and afe caused the problem... ha ha ha just kidding
 
I have my truck in at this very moment for an externally leaky CP3. Dealer says I should have it back in a day or 2. ... On an unrelated note... The 1500 gasser I'm driving as a loaner SURE FEELS DIFFERENT from my usual diesel goodness :)

I asked to drive the Dodge Charger Super Bee with the 6. 1 Hemi as a loaner... the servic e writer says... "yeah... right"



I guess i'm lucky to get a ride back to dealer tomorrow from the shuttle driver :)

Obviously it did not run ok when it went in if the lack of power and white smoke issue existed.



The fuel leak in cold weather seems to be a feature of these pumps and it has not been solved yet, but, what do you expect when sandwiching aluminum between cast iron. Expansion rates are a bit different. ;)



The CP-3 fails for a variety of reasons, fuel quality, fuel pressure, water contamination, and just plain lack of QC from the factory. We have generally crappy fuel in the states. The stock low pressure fuel system is only borderline adequate in most cases. The filtration is totally inadequate by Bosch standards. Most of the pumps are now made in parts of the former Soviet Union. If you can nail down even one of these as the culprit fix it, and just be happy they are replacing it under warranty. :)
 
Leaking in cold weather? I was aware of a dimension change in either the CP3 mounting flange or the timing cover to eliminate an oil leak but haven't really heard about fuel leaks too much here in Alaska. :confused:
 
I have an 05 with 21,000 miles and it's been replaced twice. The first time they rebuilt it and it failed about 2,000 miles from home. The second time they just put a new unit. We'll see how far this one goes.

I know the feeling the one I always end up with handles like crap, has no power and is no where as comfortable.
