Hey guys,

I am working in Iraq and we are starting to see some of the 6.4's show up over here. The biggest problem we have is that ULSD is very rare here, and I expect to see some DPF problems due to that. I have a customer bringing in a 6.4 today with a no-start problem. Does anyone have any tips on troubleshooting these things? I have NO technical information available so any advice is appreciated.

 

Obviously you have computer access and posted to this forum. A zillion posts both good and bad about the 6.4. My own experiences have been without a problem. I have around 3,300 miles on my F-350 6.4, but I only use ULSDF, maximum 15 ppm sulfur.

If you can get your hands on one of the CD's given with all 6.4's here in the STATES, you can gain a lot of 101 info.

Hopefully someone else will pick up from here, but commenting only from what I see on TV, you probably have water in the fuel, and the codes and dash lights should confirm, fix easy, drain water from under truck, driver side, inside frame.

 

The biggest problem we have is that ULSD is very rare here, and I expect to see some DPF problems due to that.

Chances are fair that the 6.4s you will see are slightly different than what we're driving over here. Ford has the capability to set this engine up so that it does not require ULSDF. This is only for vehicles that are being shipped and used it areas where the ultra low is not available. If this is the case, no worries on that issue mate. It is also my understanding the there is a "conversion" that can be done to allow them to use none ultra low. I'm sure a techie will chime in soon with a more in depth response.

 

bodabdan:

I hope Chauncey's reply to you above is correct, or you have many problems ahead. Can you answer a question? Do you represent a FORD dealer or what type job causes you to do repair work on a 6.4 PSD?

 

I run a service department for a company here in Iraq. I have been on mission to establish a Ford dealership here in Baghdad, but the politics of the middle east are quite a challenge, especially for an outsider. Ford has yet to even respond to my numerous inquiries, despite the fact that we have the nicest service facility in probably all of Iraq, as well as the land and the capital to establish a dealership in a secure location.

According to rumor, there is a company that is doing a DPF delete on some trucks before they ship them over here, but there are thousands of trucks ordered and the company rumored to be doing the conversions can only push out about 25 trucks a day. You do the math on that one.

This place is a real challenge. There is only one or two other places that offer Ford parts in the Baghdad area and the prices are ridicuous ($250 for a used ball joint) if they have the parts. I have just established an 8500 square foot service department with about a bajillion dollars worth of top quality tools. I currently have to ship my parts in from surrounding countries as there are no authorized Ford dealers in Iraq.

Thanks for all the tips, and I welcome any additional comments.

 

Read a while back on this forum where there was a 6.4L PSD export version...no DPF in order to operate in Mexico/overseas.

 

Update-

We have an 08 in the shop now with a no-start problem, 715 miles on the clock. Customer says they had water in fuel and decided to drop and clean the tank. No start since they did that. They bought it to me and I told them I would look at and see what I could do. I have fuel flow at the fuel cooler, but I was not getting any fuel to the heads. I cracked the HP fuel lines oing to the heads and after about 3 ten second cranking cycles I started getting some fuel. I closed everything back up and tried it but it won't start. I found one fuse box on the driver's inner fender and checked fuses there, all read good. I suspect that the injectors are not firing. Any advice on where to look next? Batteries were drained when we got this thing, I have them charged now, fuel in the system appears to be good, and everything appears to be in good order.
Only unusual thing is that this truck is missing something that another one has on it. On top of the fuse box for the other truck there is a solenoid of some kind that has a couple of vacuum lines running to it. On this truck the solenoid is not installed. I'm not sure what the deal is there. Any ideas out there? I appreciate any advice.

 

Any codes?

 

bodabdan:

The fuel lines on the 6.4 are single use, non seal lines (the seal is inherent in the line as you tighten). My understanding is you loosen one, replace an injector, or whatever, you have to replace that line or all of the lines if you loosened them.

Not at all like the external fuel lines on a Cummins where you have those copper seals. That might be part of your problem.

With only 700 or so miles it is hard to believe anything major could be wrong because I also read it would take several tank fulls of high sulfur fuel to really plug things up, althgh that too could be the problem.

 

no codes, and no telling what the owner did to this thing before it came in here. I have a new set of fuel line seals on order, but no telling when they will get here. Does anyone know where the IPR is on this thing? I'd like to check oil pressure coming out of the HPOP and try to check the IPR. Man, what a challenge to get to the good parts on this truck. Thanks for the tips, I'll keep fooling with it until I i fix it or break it properly.

 

bodabdan:

Reference your statement: "I have a new set of fuel line seals on order," ...

Am I wrong? I thought there were no seals, that you have to replace the fuel lines. Big difference in price. Which is correct if you know. THX

 

My typing skills have let me down again- I meant to say "fuel line with seals"

 

Thanks for the reply. I am just preparing for a day that I hope never occurs when an injector fails and I have to take my truck to the shop, and a super techie, tells me NO NEED to replace the fuel lines. Once you tighten and crimp, that's all folks.

 

OK first things first.

Here is a link to the 6.4L Bible (CLICK HERE)

After looking the Bible over, list what tools and scanner you have on hand specific that can, might, would or should work on the 6.4L

I will give one of the techs a message to come over here to this thread and look over what you respond with.

Located in Iraq my first thought is dust, sand and what the engine filter looks like, so I will not speculate. Read up and lets get down to priorities instead of second guessing.

 

you have an air lock. there is a speacial bleed tool that ford has issued to get rid of the air but tiwill tell you how we did this before the tool. remove the fuel filter on top of the engine to make sure you have flow. then depress the schrader valve on the fuel cooler supply line untill you get no more spitting of air from it and it may take several key cycles to do this. then crack the fuel line return on the passanger head located right above the primary alternator (hopefully you do not have 2 alternators). then just crank on it. you should get fuel out of this line and when you do, you are making progress and should be starting soon if everything else is ok. let me know if anything else occurs.
