I went up to the cabin this weekend and after about in hour the truck would act like its falling on its face. no power at all. It seems to only do it at 55-65 mph and 5-10 psi boost. If i floor it, it seem like its flooding out and some times it clears out and some times not. The only thing that i have done to it lately is change the fuel filter about 250 miles a go.
Question #2 if you guys have your truck in park and you rev up your rpms to 1400-2000 does your truck act like its running out of fuel, farting or studdering really bad and smokes a lot? It wont build up over 2200 rpms. Could this be a bad lift pump???
Any info would be great.

 

Lift pumps have different symptoms, depending on the truck, and some have no symptoms at all. What you describe is a prime candidate for a lift pump problem, but not guaranteed. I'd check that first though. You should also check your fuel filter. I got 6 psi in fuel pressure just by changing my filter, so I KNOW it can be a factor. :<br><br>Chris

 

Mine does it on long steep downhills. No throttle and nothing but large amounts of blue/grey smoke with an occassional backfire. Other than that it runs and starts well. Is taking longer and longer to snap out of it when it does do it. Dealer is replacing vp44. Code set was 0216 injection pump timing failure. Had to wait for the part to come in, going tommorrow for the replacement.

First thing they did was check fuel pressure and filter.

 

I checked the codes and the only one is 1693. I have a fuel pressure guage on its way so ill see what happens then.

 

Today i also seen that when it hesitates the turbo DOES NOT spool up. The turbo temp is also high, 600-650 at 70mph normal is about 500 before. My boost don't seem to hold all the way through the acceleration. When i floor it, it goes to 19 then 20 but when it shifts it drops to 16 and slow go's back up to 20. <br>I checked the codes again and i now have the 0216 code and the truck is at the dealer but they are saying maybe its the injection pump, or lift pump but unsure untill they can dig into a little more. <br>What do you guys think? Any info would be great...<br>thanks<br>

 

I won't rule out an injector pump, but the lift pump and the filter must be checked first.<br>There's someplace on this site where the code definitions are listed, but I have been unable to locate it.<br><br>Chris<br>

 

Well the 0216 is injection pump timing failure. Which was the code mine showed. They replaced my vp44 yesterday. Only driven home and to work so far so can't say for sure if it fixed my problem but it does seem to be quieter and more responsive. Will find out this weekend when I go out of town and over the the Rocky Mtns. going down the passes is when mine was the worse, major blue/grey smoke even backfiring. In town it just ran a little off (or it seemed to me that it was but not really anything real noticeable) but enough to set the code as it was cleared several times. They did check my fuel pressure and filter first though before they decided to replace the vp.

 

The ******* called and told me that it is the lift pump and they will warranty it this time but they know there was a after market fuel box on the truck so next time it will be out of mine own pocket. I played dumb I asked them whats that, they said the 5star warranty place said with all the info my ******* gave them there is a some type of after market fuel box and those VOID the warranty. I want to know how they know i have this edge ez box. Edge says it was undectiable... Anyone else have this problem?<br>

 

Rumor has it that the Dealers now have access to the Cummins DRB tool, it digs deeper into the ECM/PCM and can pull up stuff that the fueling boxes put in there.<br><br>Previously the Dodge DRB couldn't dig deep enough.<br><br>You might be one of the first victims of this.<br><br><br>phox

 

So the Cummins DRB scan tool can see that some has been messed with? I though this thing was invisiable...

It used to be, with the tools the Dealers had access to.
And they didn't want to spend too much time researching into problems.
STAR, the warranty place, is cracking down on modifications.
Dealer really has to jump through hoops to get something covered under warranty anymore.

I had my VP44 replaced almost a year ago.
No fueling boxes, no bad lift pump, just a bad VP44.

It took a week to get it replaced, many calls to STAR, much more diagnostic stuff, looking at wires under microscopes, looking for evidence of tampering, etc.
STAR doesn't let the Dealers stock them, they have to be ordered, so that adds some time.

There are a couple of TSB's that address modifications, and tells Delers what/where to look for them.
The first TSB talked about &quot;velcro or adhesive residue on the fuse box&quot; evidence of the EZ.
Then the piercing boxes came out so TSB's about &quot;wire piercing evidence&quot;
Then the Blue Chip Cover, so TSB revised to include it and what to look for.

Previously &quot;invisible&quot; or &quot;undetectable&quot; modifications are no longer so, the &quot;EZ&quot; or the &quot;Blue Chip Pump Cover&quot; to name a few.
I wouldn't be surprised if they start pulling injectors and flow check them to make sure they aren't RV275's instead of stock when someone comes in with a injection pump problem.

The Cummins DRB being made available to the Dealers is the latest move on STAR and DC's part.

Just supports the &quot;If you wanna play, you gotta be prepared to pay&quot;
or &quot;I am my own warranty station&quot;

I have a VP out of an 02 ETC with 20,000 miles for sale

it was replaced to get rid of a stumble

I still have the stumble
and now have two good VP's :'(

 

Well the dealer said it was the fuel (transfer) pump and replaced it. But they put this on my file now. DRB checked codes for inj pump timing, ect volt, 216, 217, 117. contacted star and ordered the pump and star suspects of engine enhancing devices on truck. No warranty on inj pump...
This sucks... Does the ez really hurt our trucks inj pump???

The EZ shouldn't affect the inj pump at all.
It was just coincidence that your transfer (lift) pump failed and took out your VP44 while you had an EZ on.

If this would have happened a couple months ago, you might have been covered,
as the Dealer couldn't have detected the EZ.

You must have walked under a ladder, or broke a mirror

You might have grounds to fight though, since STAR &quot;suspects&quot; engine enhancements.
If they don't have solid proof then they can't deny warranty coverage, per the Magnusson/Moss Act.
You might go to the Dealer armed with that act.
Do a search on the internet, you can find a bunch of information about it.
You're conscience might bother you though. :
