Got the truck back yesterday from the dealer. I had the fuel pressue tested (here's some back ground on it) and I took off the comp (no wire tapped, yet).

My fp gauge was acting like an 87 yr old grandmother shaking her finger at her grandson for playing with fire. It would read 16 psi at idle, then drop to 5 and back again to 16. At cruise, it would go from 12 to 5 and back to 12. At WOT, it would go from 10 to 4 and back to 10.

I took it to the dealer saying that my fp was low. They did a flow and pressure test. They said that my fp at idle was 10 at idle (minimum by their specs) and 5 at WOT ( min. again by their specs). Flow test was 50 fl. oz. in 30 seconds, 48 min by their specs. I told them I wasn't happy, and $160 later, I was on my way w/ the same lift pump. I told them that I would be back soon w/ a failed injection pump. They said ok, see you then.

I plan on tapping the wire w/ a TST grabber, hoping that they won't notice (fingers crossed, and a kinda dumb dealership). If it goes out soon, and I'm guessing that it will, then I'm gonna raise hell and make them pay for the towing fee over to the dealership, along w/ the new injection pump. What do yall think? What would yall do?

P.S. This lp has 6000k miles on it.

 

So, basically everything was right at the minimum required by their tests.



Maybe they need help with the definition of minimum?
Minimum means the pump is barely working.

Wait a couple weeks, if it's at minimum now, it will surely be below minimum quite soon,
or they'll be shelling out $1500 to furnish you with a not only a new lift pump, but injection pump,
and paying the towing bill to boot.

Drive it like you stole it! Put both pumps out of their misery, that way you can tell them "I told you so!" and watch their expression

 

I would call or go to another dealer because if I remember right those numbers are to low for DC. I dont recall them caring much about idle pressure but if WOT pressure is below 7 or 8 psi then you get a new LP. Now I do remember that the test procedure is up to the dealer. Meaning they can do the test WOT in N or while driving. Of course driving will give lower numbers. There was so many LP being replaced a while back that DC made the dealers call ahead with the results and then they would send a LP. No lift pumps were in stock. If you didnt get your truck from that dealer, they probably dont give a rip about you or your truck. Funny thing is for the $160 you just spent you could have bought a new LP from a Cummins store and been done.

 

Well, I feel like a jack@$$ now, I didn't even think about that. But w/ the lp still in "safe" parameters according to the dealer, and I didn't think it would be, I had to pay for labor. I thought for sure that they would replace it, thus me paying nothing via warrenty. Oh well, too late now. Only one thing left to do, tap the wire w/ the grabber, blow both pumps, massage the wire to help conceal the tap, make them pay for the tow truck joy ride over there, throw the keys at them saying I want 2 new pumps and I TOLD YOU SO, and be on my mery way w/ a million dollar smile on my face!

 

Use caution if you tap that wire,D/C has sent out numerous bulletins on how to find evidence of tampering,including descriptions and pictures of tapped wire.When the pump is sent in it will be inspected,if tampered with the claim will not be paid.D/C and the dealer have the option of chasing you down for it.The word Fraud comes to mind.Good luck.I love my 12valve.No electrons haunting me

Might help some folk out and save some money...Lifetime warranty is a good thing.

 

If they don't ask what was on it, why should he tell them what was on it? I don't see anything wrong with that.

 

OK, been a few days since the rig has seen the dealer. On my way to dinner tonite, the fp never went above 7 psi, even at idel. For 3 or 4 miles, on the 7 mile trip, my fp was 0, yes I said 0. I'm gonna unhook the comp (which is still on ez mode) and see what happens. I'm soooo tempted to go to the dealer and make them replace both of my pumps. Wait, I'm just gonna wait til the truck don't "go" and make them pay for everything. Something tellls me that even before I get a chance to tap my wire, both pumps will go out, which I hope that happens, just to make my life easier. Oh well, we'll see what happens. I'll keep yall posted.

I also would be a little leary of a dealer like the one your dealing with. You might not want to tap that wire just yet. See what your pressures are without the comp and if they are still to low I would go back and demand the money for the last visit. Then make them give you a new LP. But I truely think the first numbers you had was to low. Try calling some other dealers and ask them what the LP pressure standards are and what do they go by. I bet you'll be surprised to find that you got burned.

 

So your driving along and the fuel psi drops. Is the lift pump failing? or is it a problem upstream?....Your gauge indicated a perceived problem, but is the pump going bad? or is something ahead of the pump letting excessive flow by causing the psi to drop.

 

my dealer here told me 12 psi at idle and 9 psi at WOT was the minimum!!! So basically that dealer is trying too screw you!!

 

Those dealers don’t care about anyone but themselves. I had the same problem, my LP was acting up so I took it in thinking it was be replaced. It even sounded bad when I bumped after replacing the fuel filter. They said it was putting out enough fuel for their requirements. So the basically said sorry, bye now. I put up a stink and went on my way wonder what the problem was then. Two weeks later I’m driving on the freeway and my truck starts to sputter. Look behind me and there is all sorts of white smoke, pull over and as soon as I hit the shoulder, my truck dies. Get it towed to the same dealer and they say (4 days later) that they replaced the LP but the IP is fine. I was mad, think it did any good? Nope, they wouldn’t touch the IP since the truck ran fine for their drive test. The LP was covered by the warranty, but they wouldn’t even pay back the $40 bucks to have them test the fuel pressure that didn’t work worth…. . I just wish Cummins would put their engine in a Chevy! I hope I didn’t offend any one with that comment but CTD is the only reason I bought a Dodge/Chrysler product. Sorry so long I'm just a little upset about all this.

 

You guys must be mad about all the crappy service down there in the states....I have never had any problems up here in canada....In fact if i even think something is on the fritz, they will replace it too keep me happy!! Must be because us canadians are more friendly...LOL

 

It really sucks when you get linked up with a mech. that does not appear to take pride in his work. I try my hardest to avoid dealer shops unless an independent mech recommends the dealer for a certain job/problem. Indepedent mech understand that if they PO enough clients they will not be back next year. Dealers can go belly up due to poor service too but it is alot more uncommon and event. I wish you luck in solving them.
Anyway, beyond the LP pressure gauge acting up did the DTC change in performance at all if so what did it do?? Beyond the LP pressure gauge that you installed, what other guage have you installed to monitor your DTC operation.
