Had a performance problem

[Yo Hoot]

Felt like low rail pressure. Felt like it would miss on hard acceleration. . pop once in a while. Started to worry about injectors and pump.....



Changed the fuel filter that had 20,000 miles on it.



Problem gone

no check engine light?

With the mods I have I get CEL's all the time. They come and go. High boost spikes and such.

Well this just isn't what I thought this thread was going to be about at all.

Did you read the codes to see if there was anything that sticks out?

I used to but don't bother anymore since it runs great. I also read that it's common with the PowerMaxCR

The reason for this topic was to remind everyone to change the fuel filter regularly.

 

[Prairie Dog]

Mine did exactly the same thing when I had a plugged FF from a bad tank of fuel.

 

[Yo Hoot]

I feel like I have a new truck.

Funny thing is FASS pressure reading is no help.

 

[Prairie Dog]

You must be taking the pressure reading before the FF?

You must be taking the pressure reading before the FF?

That's what I was wondering.

Yo Hoot If the filter was contaminated to the point of power loss,,My guess is you will also be experiencing a wallet with draw within 6 months or 10K miles.

Yea I here ya but I didn't let go for too long. I don't think the CP3 is as susceptible to damage from low fuel volume as the non CR pumps were anyway. Look at the early Duramaxes. They operated under negative fuel delivery.

 

[Prairie Dog]

You didn't hurt it one bit. The same thing happened to me about 5 years ago. I had to change the filter twice within 200 miles. Eng would miss just like a gasser with bad plugs and this was while on a trip and towing heavy. Of all the lift pump failures I've read about I've never heard of fuel starvation hurting a CP3.

 

[TCDiesel]

Yep. . my recycle Guy Just took the Pile of CP3s destroyed By lack of Fuel or cooling... NON-OEMs,I here the same story over & over again. By the Way. . Were did I mention CP3 damage form this? The keystroke TDR kings strike again. Yep. . 2 victims this week on the multi filter direct injection failure. I am not going into details (its Just wasted time) My Bank account love the INTERNET.



Members and guess don't be fooled By the social network reports they are only 3% of actual at best,Of course there is always the exception, but you would be foolish making rules form the exceptions.

Oops, sorry but I tripped over your ego on the way in. I do have to acknowledge that at least you made an semi-intelligible post this time, though obviously a line of B. S. and self promotion.
It surprises me not at all that your "experience" differs from every one else on the "INTERNET". I've noticed that your experience of the week always shows up just in time to trump the "social media" - how very convenient for you.
I'm tired of your arrogance, your pomposity and your lack of respect for the many here who are at least as knowledgeable as you and in many cases more so. The people of TDR have far more experience as a whole than you ever will and they give they're advice without any hidden agenda or desire to be the know-it-all.
So I'm going to join the legions here who have to call B. S. on your posts and this is the first one.
Now why don't you threaten to take all your toys home and never talk to us again - that one never gets old.

 

[TCDiesel]

You didn't tip my Ego... I Don't base any judgment on 1 vehicle. . You are entitle to your Opinion like always. By the way Ego, Covetous, Jealousy, and Pride, I work hard at saying away form. . But don't you think that BC it did NOT happen to YOU that its the same Way in every CASE, thats what separates Me form the TDR keystrokes Kings.



Keep Your social Media 1000s of times has it proved to be False, its time to get in the real Game. Agenda Look in the Mirror.





What toys? Now will the real Praire Dog step forward.



Yo Hoot I get many calls for Injection compo-nets R/R ETC, Many times I hear the same Comment, MAN it was some time back I had to change MY filter(s) due to poor running or loss of Performance,its just 1 common denominator, I hope you are the exception just the same as anyone else, but if Not just a little heads up.

 

[Yo Hoot]

How do the early Dmaxes get away with sucking fuel from the tank? CP3 has it's own gear rotor lift pump... what's that for?

 

[TCDiesel]

The D-Max and all CP3s have a Gear Pump that will Produce 15-25hg the D-Max filter is designed to filter with Vacuum,the Filter Head has a hand pump that will prime the entire system back to the Tank, What happens with the Cummins Apps is the aftermarket has fooled the owners into thinking you are at No risk running pressure before filtering with Suction,You increase the risk with Higher running higher pressure with suction / vacuum, thats Why you had NO indication on the Pressure gage until it was to late and Performance loss was attained, this subject was hammered back a few months ago. I gave up on the discussion.



This forum and others have much valve, its the social network were You need to separate the weeds form the wheat. Over the years I have benefited form Your posts and threads,I just wanted return the favor.

A couple years back, I lost my FASS on the way back home... drove over 2100 miles without a lift pump, highway speeds, 1000#s of brick in the bed, from Washington to Pennsylvania. That was probably around 210k, I sit with over 266k on the ORIGINAL CP3 THE TRUCK CAME WITH FROM THE FACTORY (and the last 100k with a Smarty JR).



I guess actual experience doesn't matter? I know when I sell this truck in a month or so, I will not miss your holier than thou posts one bit.

Eh? Your too kind. I think I know what he is trying to say but it would be much easier reading if he could just SAY it in plain language. :-laf

Talk to the Dmax guys and pump rebuilders about how that works out, its not that great. Addition of an LP used to be worth 20-25 hp and they quit eating pumps up at an alarming rate.



The Dmax setups have larger fuel lines, the CP-3 sits in a much lower location in relation to the fuel tank, and they have a different gear rotor pump that is supposed to accentuate the no LP design. Its not a fair comparison to the Dodge\Cummins installed design.



I think what Todd is trying to say is by the time performance has been effected and noticed the CP-3 has been short of lube and cooling for a much longer time.



A lot will depend on your filtering. If your running the typical FASS filters and OE cartridge and plugged them you have probably run a LOT of crap thru the system in addition to lack of cooling\lube. If it was true 2-3 um filter then all you have to worry about is the lack of cooling and lube. Either one is a death sentence on an HPCR pump.



I am surpised you did not see the pressure drop at the CP-3 or rail pressure drop sooner.
