Anybody out there have an idea of what might it be.Sometimes when I first start the truck(unplugged )with the remote start it acts like a (pardon the expression ,a v8 running on to two cylinders).It also did the same thing with the key start but only once.I have changed the ff since it first started,but it still happens,and sometimes it will run so rough that it will actually stall out.It has had the pump replaced to the tank about a year ago.
My knowledgeable parts guy suggested either the grid heater may not be working properly or maybe a injector.But my thoughts were if it was an injector wouldn`t it do this whether it is plugged in out not.
Anyhow it is going into the dealer here to get checked out.I `m just under the 160 mileage so time to get it looked at.
Any info given is good.

Sounds like injector time to me.

I'm new to 3rd gens. It sounds to me from what I've been reading that there are 2 things to watch. lift pump; injectors.

when you start with the key it wont run rough?

It actually has done it both with the key and the remote start.But I have not noticed it if the truck has been plugged in.
Anyways the truck was in the shop today (all day) and they an injector test and it came back fine.But they did find that the "Pressure Limiting Valve " failed.I was ask if the truck was chipped and said yup.He said that if Dodge requested the computer info that they had to give it to them and if they felt that the chip was the cause of the parts malfunction then they could or would void the warranty.These guys here seemed very good about it though and put it though on warranty.
The question that I put out to all or any 3rd gen techies is would the 70 hp edge cause this part to malfunction after being installed for 2-3 yrs.Or could `ve naturelly failed.If it was caused by the chip is there a better replacement for it.Or would installing some larger injectors bring down the pressure so as not to harm the pressure limiting valve.Thanks for the help.....Kev

Pressure limiting valves have been a fairly common failure. Especially with the 03-04.5 engines for whatever reason. There were many injector sets swapped out pre-maturely when this little valve was the culprit. Good to hear you got it under warranty anyway.

I believe the EZ is a pressure only box. You could try a Smarty or similar for more enhancements to pulse width/timing etc.

They said that it would have been an $800.00 touch.Ouch .Good thing for warranties.So if this valve fails it can ruin injectors,or I`m I reading this wrong?I don`t want to get to wild with this truck maybe it 400hp,but definitly have to do the tranny to handle that (47r).

They loaned me a vehicle while mine was in the shop(pt crusher) I drove it a total of 30 mins.Man I missed my truck.

Shouldn't do any damage to the injectors. It was just sticking open probably and bleeding the rail pressure down to below usable pressure. I would think in this day and age with the CR engine, 400hp should be a breeze..

My 04.5 seems to be giving me some grief now too. Sounds almost as you are describing Kevin. The last 2 days just after I start my truck it would sound like a bad knock and long crank time. This was while the truck was warm. Real touchy fuel pedal and surging. Shut it down and restart it a few times and everything was back to normal. I had 8 or 9 different codes that I have written down in my truck. Will get them in the morning........

You got fuel at the injection pump? How much pressure you got at the injector connector tubes? I would crack connector tubes open and see how much fuel you got. If it sprays lots, you got an injector problem, if its weak stream see how much fuel pressure you got at your injection pump. I do this stuff with my VP so hopefully this help you. A decent diesel shop could do the pop off test to see how the injector flows.

Swampy, I've got an '03 manual if you need to decipher the codes.....

Not to butt-in or anything but I may have to take you up on that sometime in the DISTANT future Jason. Hope not but you never know.
Andy

Well,so much for it being fixed.I have yet to plug the Edge back in and today my truck sat at work for 8 hrs and I went and started it to leave and it happened again same issue(run like a v8 but on 2 cylinders,wants to still out).If you keep working the throttle I can keep it running.Tuesday it is back in the shop.More advise on what it may be....
Thx Kev.

I still say injectors.

I`m not much for shopping at the dealership,there prices seem so high.If I was to replace the injectors with stock ones from dealership they wanted $800.each.I am surprise at the price I will do some online window shopping over the next fews days.

Not butting in at all Andy-I would be happy to supply you info etc....

Here's an open question which is kinda stupid....does an '03 spit out codes like my '01 by cycling the key 3 times? And if so, when did they quit doing it-or did they? I would assume with the switch to CANbus in '06 those trucks will no longer do it-but will any year of DR truck?

Thanks
Jason

See if these codes point you guys in the direction of my issues!

P0237 Turbocharger Boost Pressure Sensor Low
P0193 Fuel Rail Pressure Sensor High
P2269 Water in fuel condition
P0340 Camshaft position sensor circut
P0341 camshaft Position Sensor Performance / Rationality
P2127 Pedal Validation Switch 2 Low
P2121 Pedal Position Sensor 1 Performance / Rationality
P0652 Sensor Reference Voltage 2 Circuit Low

In the last 30 or so starts it has done it to me twice. Both times I was sitting for awhile listening to music draining down the batteries some. When I jumped in the truck I just fired it up and take off all the time never waiting for the grid heaters to cycle. The alternator is not charging both times while this was happening. It does charge after 20-30 seconds. I have a smarty coming to clear codes and think I am going to clean battery posts and grounds etc and see what happens!

I don't know. I need to learn all that yet.
Andy

Wow....I am not a 3rd gen guy-so I will reserve final judgement for one of the gurus. Here is what I think: 1st and foremost, if you're taking it in for service, you best get the codes cleared as the "water in fuel condition" will surely nullify any warranty you may have left as far as injectors go. Did you have a box on it once upon a time? Maybe that would explain the low boost and high rail pressure codes....I don't understand the camshaft and APPS codes though. The DRB-and probably some fancier aftermarket ones like Snap-On or OTC (who actually make the DRB) can tell you how many starts since each was set-I would wager they were not all set at the same time-but possible I suppose. I would try cleaning connections etc. 1st as the easiest thing to try....

Hopefully someone with more CR brains than me will chime in. I wish I was closer to offer a more direct hand...plus I'm sure we would both learn something.

Jason

Clear your codes. See what code comes up when it does the funny idling sound. Have you checked for fuel pressure? You could have a faulty engine speed sensor. You need that to fiqure out when to fire the injectors, its all computer controlled not mechanical like mine. I would see if the well the injectors flow path looks and replace the crank engine sensor. My truck its not to hard to pull that engine rpm sensor, its right under the injection pump.

No warranty to worry about on the 04.5 I have had a Juice with Attitude on it for the last 3 years. It has the hot program if that matters. As for the water in fuel, I have no idea why that code came up. As soon as I figured out what the code was I took a sample from the fuel filter and it was pure diesel. 205,000 kms on it anyways! Been buying from UFA for the trucks whole life and never had a problem before. Guess there is always a first time...... Also been using amsoils diesel fuel conditioner every tank for the last 6 months. I believe it separates the water.

You should have seen a water-in-fuel light anyways if it was real...I just figured you might still be under warranty. 205K-man, do you ever stay home? [laugh] Poor old Silver only has 413K on it and it's an '01...

I have run UFA fuel for the last few years-if it wasn't convenient for me I probably wouldn't-I got better mileage and better power out of Petro-Canada down here-and it was cheaper than UFA-but when they shut the cardlock down that made it all irrelevant.

I have turned my DragCOMP on about 4 times in the last 2 years :( but I got some flaky stuff out of it at times-wonder if it is contributing to the problem or if it is something else? The no-charge situation makes me wonder about a flaky ground etc....

Jason

The no charge situation, I'd be looking at either the cam sensor, or the crank sensor if they have them. Since you have a cam sensor code, that would be my guess at that. It may also explain the high rail pressure code, since it would be seeing rail pressure when it thinks there shouldn't be any (engine running, no cam sensor signal, thinks engine is off).

Check the shorted wire thread on 2003-2007 DTR (top sticky). Souds awful amiliar to your problem.
