I am having a problem and don't know what it is. I was on the way home here a couple weeks ago and got the dead pedal when I went to pass a car on the freeway. I was about 10 mintues from the house so I went straight to the dealer and had em check for codes. I got the injection pump timing failure code. Great that's all I need, I got 40,000 on this injection pump and it's acting up. My fuel pressure is at 15 idle and around 11-12 at WOT, it has never gone any lower as of yet. I run the comp on level 2 or 3 tops for my daily driving, I have had it on 5 2 times since it has been on the truck just to see how the truck ran with it, once to make sure everything was working and once to show my wife so she could mumble ugly things at me. The mechanic and I discussed it and they cleared the code and said if it does it again bring it back. Well nothing happened for about 3 weeks now until Last Friday. It did it again so I went back and it threw the same code. We spent an hour trying to figure out what the deal was because the mechanic said it didn't sound like the pump to him so we checked the APPS Sensor and it seemed to be ok as well it checked 3.5 amps and 96% throttle response at the floor. Well it did it again Sat. 3 TIMES. It runs fine and accelerates fine until I have driven the truck for a while, an hour or so. When I pass a car on the freeway it is ok until the next time I go to pass someone. I get the dead pedal, it won't go no where, it doesn't lose speed or any RPM it's just dead. I have noticed that every time it does it I'm doing 70 - 73 and around 2200 rpm or so, if I push in the clutch and push on the pedal the rpms shoot up then I let out the clutch and it goes back to normal acceleration. I am going to go back to the dealer today and have him hook up the scanner and go for a test drive with me to see if we can duplicate the problem and figure out what's up. I wanted to see if you guys can give me any thoughts on this one and maybe what else to look for. When my pump went out last time it was extremely hard to start but this time everything works fine except after I have driven for a while. This makes me think it's the pump since it only acts up after it's good and warm but I am not sure. the dealer isn't sure either, I don't wanna spend a couple grand on a guess only to find out we were wrong. The next part of my question is if the pump is bad what are your thoughts on a replacement option. Should I go with an after market pump such as the hot rod pump are there any advantages to this? Are they really any better, do they last longer. I am gonna look around for the best price but as of now Dodge wants $2,016.00 for a new pump, I can buy the hot rod pump for $1600. What do you suggest?

 

DO NOT buy a pump from DODGE!! Whether hot-rod or not you can get a cheaper pump direct from Cummins. Piers Diesel offers some nice pumps. You can also find them at many injector,turbo shops that are Cummins dealers for arpound 1100 to 1200 bucks. I am not sure about your problem though. I am having my own battle with the APPS.

 

Sorry, I should have mentioned that I can buy the factory pump from cummins for $1300, was just making the comparison to Dodge.

 

Calls, that is exactly how my truck acts. Only difference is in the mornings it suffers the dead pedal thing until the truck warms up (about 2-2.5 miles at 35 mph). Then it will run fine for a while and then dead pedal again. Next time yours does it, cycle the ignition key off/on while driving and see if it takes off. Mine will run like a scalded ape when I cycle the key. Mine has been acting like this for over 48K miles and I don't want to drop the 1.5K out of my wallet till the chihuahua croaks. I know it is injection pump related but I can't figure out why it reacts as it does (and has for so long).

If you and your mech. find out any additional information, please give me a PM.

Thanks

Gary

 

I know with all the knowledge on this site some of you have an idea as to what my future holds with this issue. Any ideas guy's...any?

 

I have the same problem. It first happened almost a month ago, and has only happened once since. But if I turn the truck off and let it sit a little while, the problem goes away. I am on my second vp as it is, but the last one went all at once, and left no doubt about what the problem was.

 

If you had the "injection pump timing failure" witch would be P0216, your pump is dead. I can't believe the mech. is unclear to what is going on. Your pump is gone. I have gone through 4 vp44's, now on my 5th one, I know the symptoms ...I have 79,000 miles on the ol' 2002. As long as it is still under the 100k mark I will let dodge replacem for free. After the 100k and it dies I will go aftermarket.
Your truck could run great for a day/hour/min/month, who know's, but your pump is still toast.

 

I think the code could be a fluke for the VP44 being dead. I had one the other day, yet I know my problem is APPS related &/or electrical. See my topic APPS. Mine is continuously doing this dead pedal thing.Die & run, Die & run. Even got an 80 MPH speeding ticket today because I stuffed it on the floor & the **** throttle hung on me. Jerk-off cop didn't care about my truck problems. My truck is just a nightmare right now & I can't find the problem. Calls I am on my 5th VP as well,250K miles. The original came off at 99,900 miles. The next one came off 3 days later. The Darn Blue Chip boxes were so hard on them. Dodge hadn't got the notice about the clipped pump wire yet so they replaced it. The third one held up for 12k more then I had to bite the bullet. Then Cummins screwed up & sent me one for free, NO JOKE. It is the one I have in now. Other than the first one, they all immediately let me know when they were gone, cause I had to call a tow truck. Keep driving it & check the codes periodically to see if you keep getting the VP Death code. I would go ahead & start saving some twenties each week as you will soon need them.

 

I'm still wondering what everyone thinks about the after market pumps? Are they any better, more reliable. Do you think there worth the extra $300? I am more concerned about reliablity than I am the extra hp?

 

Calls just buy you a stock replacement pump that is warranted by Cummins, if you are that worried about the reliability. I can't speak on any of the after market pumps, as I have not tried one. I guess you aren't going to get a response from anyone that has tried one, so Stay away from them. If somebody won't warranty their product for at least a year, I wouldn't buy it. If you are going to pierce that wire again, it isn't going to matter. It's up to you. I think I will be trying the PIERS high performance pump when I have to buy again, unless there is something better out there.

 

Man was I wrong, I just got off the phone with Southern Plains Cummins in Houston and they said the price of the pump from them was $1734 with a 12 month unlimited mileage warranty. I talked to the parts guy at dodge last night and he said he would sell me the pump at cost which is $1300. Man what's wrong with this picture a part is actually cheaper at the dealer instead of cummins or I could get the hot rod pump for $1600, I know that cummins is out of the picture for sure but I still wish some of you guys that are using one of the after market pumps would chime in here please. I would really like to hear your opinion on the pump good or bad.

 

Calls,
Try calling Freightliner parts, 713 6728668. They are a Cummins parts dealer, located off of 610 and Wallisville. I have found them to be fairly reasonable for OEM parts. $1,700.00 seems higher than a giraffes butt for a pump price.

Good luck,

Gary

 

This is the same problem I have on my truck. I am replacing the overflow valve today or tomorrow, and hopefully that solves the problem. If not, I gotta spring the cash for a new IP.

Would the overflow valve cause the code and the dead pedal. I have not heard of this before and have been setting here readin gup on some old post about it but none of em say that it will throw the timing code in the pump What exactly am I looking for? How will I know if it's bad or not when I pull the line loose ?

 

The bad Overflow WILL throw that code. It will also cause the dead pedal. I am goign to try it today and see what happens.
