First set of new injectors from dap, had to send back for warranty, put 2nd set in then had to do the same thing again. With this being the 3rd set am I just having really bad luck with injectors or is something else causing it? 

I keep getting a knock/ping and sounds like a bad miss if u (more prominently)coast and very lightly tap or ride the throttle and just runs rough/ just not how it should. Runs rough and knocks when normal driving the same just more so as stated above.

Why do I keep getting this knock etc? Is the vp44 causing this to go down stream? Fuel psi is consistently 16psi, no codes or check engine light (doesn't mean awhole lot but..) 

This has all been in a very very short period of time. The last thing added was the quadzilla adrenaline but I don't see it being any issue? 

 

Only things I can think of is 1- injection pump (runs great) 2- injector lines or tube (mating surfaces looked good) 3- just getting bad injectors. 

 

What the heck?

    Smoke will come with wire tap trust me lol. Lets get injectors figured out first then go from there

    Yes it looks like a standard 028 HO core.  We can take it for an 027 SO.   Let the sales guy know it is approved and we can get the pump going for you.   As @Silverwolf2691 stated

    6-700hp is what stocks are generally good for.. possibly more.   Hell the factory cam and intake horn have done the same if not more.. not saying its the most efficient, or absolute best pow

Ooof, sorry for that news @Stanley.

 

Quad only retains the max value without the exported data log. So all it means is that in the last 4hrs of logging (i think) you hit max commanded fueling. 

 

And yes its possible that for the timing to cause the sounds.

No I was saying that before pubg came about lol...However I do play call of duty sometimes 😁

Your meaning stock timing on bad pump making knocks in the injector  correct? Not the timing from quad...

When the P0216 code is set the Quadzilla only reports commanded timing not actual. Like my last pump was stuck full advanced. Very hard knock only got 25 to 30 MPH

This doesn't explain ping following the injectors when you were troubleshooting and cracking lines to see when ping stopped and I believe you swapped the injectors and ping followed that injector also. 

But hey you maybe on to something

Take a look at the wires on the back of the vp44 that go down to the bottom solenoid. You may have to slide the cloth sheath up some. The wire insulation likes to get old and crumble away. Use your fancy Snap on bore scope.

Well if what @Mopar1973Man was saying about him having a knock and it being at full advance it could have been the pump going just not saying or showing anything.

Also really common for the timing piston to gall up and seize in place. If the is no p0251, p0252, p0253 or p0254 codes the solenoid wires are fine.

No, didnt have any of those codes on the key cycle*.

Yea it did follow on the first set. This seems just like a huge mess that may have finally just exploded to the root issue idk... I guess ill have to start fresh with new pump I understand SOVP is the way to go instead of HOVP that these 6 speeds had. I guess I might as well as, which pump is better than the other. @dieselautopower I obviously been looking through your pumps... 

Kinda curious who actually went with the 2 year warranty pump vs 1 year. Also I have read mixed opinions if you will that the stealth cover is OK to use on pump with out voiding warranty, I suspect this is false... @dieselautopower is there a pump you have that would be ok to tap out of the box? I guess running with no tap on the quad wouldnt be to bad with bigger injectors? 

Do the 2 year warranty pump.  It has a new PSG.

 

I recommend keeping the pump untapped.  If a pump is going to have problems it is typically going to be within the first 6 months.   SO pumps occasionally do not like to run on the HO engine without a code, but timing changes on the adrenaline can reduce that probability ( which is low anyways, but one should be aware that it can throw a code).

 

 

the tapped pump that retains a warranty is an option, but it is not different than the other pumps sold.  Basically paying for an extra warranty to cover a potential replacement.

Essentially the difference you will feel between the SO pumps (ETC) and HO pumps (ETH) is where the power band is.. HO trucks are lower in the rpm range vs an SO pump. Since you have only had the dragon flow, im gonna guess either pump is gonna feel lower powered than what you had. But for what you have, go with an SO pump, its better suited to the upgrades you already have. Core might be an issue though..

Galled or seized timing piston will not throw any other code but a P0216 code. Which yours did. I've seen pumps so seized up your had to heat the case of the pump with a propane torch to get the piston freed or to even slide out.

Well I dont want any codes lol But Id like more power on top for hwy rpms etc.

I think I have to assume that this is what happened locking up. Code now plus hard starts and the knock - to which is safe to say was caused by pump? And I should ease my mind and not think the worst now? 

 

@dieselautopower here is some pics of pump when I previously took it off. Doesnt say 028DF  but who the heck knows... Would this be ok for a core? And keeping those 6x13's in there with that new SOVP should be doable for awhile aye?

Large majority of people who swap an SO pump on don't have codes or issues.. odds are you shouldnt have a problem, but theres a chance..

Yes it looks like a standard 028 HO core.  We can take it for an 027 SO.

As @Silverwolf2691 stated most do not have a problem with the swap. However it is a possibility and I don't want anyone to be misinformed.

I guess I forgot about my .093 lines and tubes....

Gonna want to sell those and get standard sized stuff if you step down to an SO pump.. retards the timing, and might screw with the idle more than what you currently have

I have stock lines, idk if there any good, I assume that there the original ones from truck. Also have 1 new set of cummins oem tubes and 1 used, 1 set of used stock injectors (unknown status). I might have to take pics of lines and see what yall think. I read some where that you could run the bigger tubes just not the lines. I guess since I have oem ones I might as well use them. I think stock tubes and lines are good for quite a bit of HP before needed swap. Wonder who would want those lines and tubes? Might put them on here for sale. 

6-700hp is what stocks are generally good for.. possibly more.

 

Hell the factory cam and intake horn have done the same if not more.. not saying its the most efficient, or absolute best power, but they aren't as big a hindrance as one would think..

Wonder if the code you have now is because of an odd ball pump 

Well it just came about. After all this time idk if it would do it now?
