My Engine Died

What happened:

Was making a run from Victoria,Tx to Ft. Worth, Tx. I had just stopped and gotten fuel and was back up to hiway speed and the engine died like I had turned the key off. I was able to coast off the hiway and into a small truck stop parking lot.

What I have cked and done:

I had just gotten fuel so I thought maybe dirty fuel, changed filter, no difference. When I cked codes, I had four that were not there Monday.

P-0113 intake air charge temp sensor high

P-0193 fuel rail pressure sensor high

P-0237 turbo boost pressure low

P-0341 camshaft position sensor performance/rationality

I have also cracked a injector line to see if any fuel was getting to the injector, it is. I also took the edge box off and hooked it up stock. No difference. The engine will turn over, but will never hit. I now have the truck at a shop back at home to be cked out Monday. A friend came up to pick me and my truck and trailer up. (and deliver my load to Ft. Worth)

It was suggested that possibaly the Edge box might have fried the sensors. Anyone else had a similar problem? I'm throwing it up to the forum, anyone got any ideas?



I posted this message on 8-21 in the Engine and Transmission Forum, since then, the shop I went to did not have the right scan tool to diag. the problem, (they told me they did) but did manage to erase the codes that were there. They are wating for the correct tool but it will be several days before it will get here. It was towed to a dealer who said it had no codes and just let it go at that. The shop seems to think it is the main (high pressure) pump. Is there any way to ck that without a scan tool? Any help will be greatly appreciated since I make my living with this truck and I've been out of service since last Fri. This is a 2003 so it is not the vp 44 pump.

I have read on here of at least one 2003 having a bad pump replaced... . that's a wide range of codes though... wish I knew more... keep us posted... good luck.

Boost pressure and rail pressure codes I could attribute to an EZ, it directly affects those two systems. Have you ever disconnected the cam sensor? If you had a timing/duration box like TST you would have to so I might blame it on that. Charge air temp..... doesn't sound like anything the ecm should shut down for? Have you tried starting it after the codes were erased?

My truck is being taken to the dealer I bought it from with the assurance that they will get right on it. The shop I had it at, tested manually the best they could without the right scan tool and this is what they think it is and why.



The lift pump is supposted to put out a certain mili-liters of fuel per second, 1. ? oz per second. As near as they could tell the lift pump was putting out the correct amount of fuel to the main injection pump (pressure pump) The main pump was putting out nothing to the fuel rail. They say they are 90% sure the main pump was bad, but couldn't be sure without the proper scan tool. The dealer should be able to tell when they get on it, hopefully within the next hour or so.



As far as the codes go, I wonder if coasting down from 70 mph and trying to start the engine by letting out the clutch while in gear could have caused that.



There was another post where DCTech said he had replaced two pumps on trucks and they had boxes on them as I do. I am going to pm him and make sure they weren't vp-44 pumps because no one around here can get a remanned pump for a 3rd gen truck. If this is going to be a problem, everyone with an edge box might need to get a pusher pump to supply enough fuel. I tow and tow heavy all the time so that might be the problem.



Will be back when I find out something else.

EB out of curiosity at what level have you been running your EZ?



Thanks, I hope you get her going soon.

 

[DCTECH]

If still won't start with your box unhooked, unhook fuel pressure regulator electrical conector at pump and see if starts. The scan tool is important to see if pump is making required pressure. I show many dealers in Texas have a reman pump in stock p/n R5104871AA and Dallas parts depot has 29 in stock.

If I knew where you are I could tell what dealer is closest to you.

Camsensor code has me a little concerned...

Ok, here is what has happened. The dealer ran all the required tests and comfirmed that it is the injector pump. Not the lift pump, but the main pressure pump. There is one on order from Dallas, will be here tomorrow morning. I should be back in business tomorrow afternoon.

Now, here is the question I have for the forum, would a pusher pump of some type helped to prevent this from happening. My way of thinking is that the lift pump wasn't able to supply enough fuel with the box running on level 3 and 4 to keep the main pump lubricated and it burned up. The dealer tells me there is no core deposite on the pump so I am going to get it if I can. I'll ck around and see if a pump shop somewhere would like to take it apart and see what happened. The pump shop here has never seen this type of pump.

If it did starve for fuel and that caused the failure, then everyone that tows and tows heavy like I do need to be made aware of it and just not use the box or maybe put a pusher pump on. Is there a pump called a Hauss or something like that? Would something like that help? What do you think.

By the way, all the codes went away, they said they were probably thrown when I was coasting down and trying to start the truck by putting it in gear.

I hope the CP3 is the problem and you get rolling. That would be my guess, but I don't know these new engines and don't want to mislead anyone.



Diesel Dynamics has a pusher pump set up for 2003+ Dodges. Just a thought; I don't know anything about it.



While I am thinking, here is another thought. From what I have heard on the forums here, You would know if the CP3 was starving for fuel. The truck would stumble. From what I have heard, unless you starve the CP3 on a regular basis, it is not as big a deal as with the VP44s, but who really knows.



Good luck EB. Let us know if you get the old pump and have it torn down to know what happened.

The problem was the main injector pump, the CP3. Coming stright from the work order "no pressure coming out from high pressure pump diagnosed--replaced the high pressure fuel pump, test drove OK" the part # for the pump was R5104877AA, a remanned pump, price was $1075. 00

I'm back on the road again, that's the main thing. I'll be looking into getting a pusher pump of some kind to help the lift pump out before I put the Edge box back on. I still think that had something to do with it. What is out there besides the FASS and the AirDog?

Thanks for all the responses.
