2006 6.0 Wont Start (FYI)

[rickrod99]

I own a 2006 6.0 SD with 45k miles and this weekend I ran into something that I wanted to post here for others to read. Being that I am new at this, it was a little surprising to me.

Long story short the alternator on my truck went bye bye. We checked it and it was not charging the system. However this was after it decided to leave me stranded on the side of the road. Come to find out, and I was told this by a diesel tech friend, that if the system is not charging and the voltage drops although you may still be able to crank the engine, the truck will not start. Mine was doing just that, it would crank but not start. I purchased a new alternator and recharged the batteries and good as new.

However, and here comes the question for those of you who are techs and would like to help out, now I have an issue where when its cold the truck starts fine and works great as long as you don't shut it off when it is warm. If the truck is at operating temperature and you turn it off and try to start it after that, it will crank and start but then shut off right away. The symptoms are always the same.

I have a buddy bringing me a scanner to see if there are any codes. Here are some other questions I also have if anyone can answer them.

1. Where can I find the definition of the codes from the scanner?
2. Is it possible to read codes from a scanner when hooked up to the truck even if there is no engine light on?

Any and all suggestions would be great.

Being a 2006 model year, and symptoms you describe, I will bet money that the STC (snap-to-connect) high pressure oil pump outlet has blown out, and/or the high pressure oil rail lower o-ring on the dummy plug(s) has deteriorated.

That being said, you're only a $100 deductible on your diesel engine warranty (being a 2006 with only 45K miles) at nearest Ford dealer away from having this problem fixed.

Part numbers for this repair:
4C3Z-9B246-D (STC fitting outlet kit)
-W302195 (dummy rail plug, 1 needed per bank of cylinders)
This is provided you have no IPR valve or high pressure oil pump issues, which seems unlikely at your mileage.

1. Any Ford PC/ED or other publication that lists 6.0L diesel specific DTC definitions.

2. Not all DTCs (diagnostic trouble code) will set the MIL (malfunction indicator lamp) on. You COULD have what is called "continuous memory" DTCs, which means DTCs that were set at one point in time, but not currently active at the time you connect a scan tool to read them.

Regarding your specific issue, you COULD have a P2290 and/or P2291 set, which would be low ICP pressure DTCs.

This particular engine uses engine oil under HIGH PRESSURE to control fuel delivery from the injectors. The fuel pump (or more specifically the HFCM on a 6.0L) control supplies the volume of fuel to be delivered, and the high pressure oil pump controls the fuel pressure at the combustion chambers under various operating conditions, depending on driver input. The IPR (injector pressure regulator) controls the amount of high pressure oil needed under various conditions (again, depending on driver input).

Thank you for your reply. I do have more info on this. I had the vehicle scanned today the error codes I got were:
P0404 Exhaust Gas Recirculation circuit Malf.
P0405 Exhaust gas Recirculation sensor A Circuit low.

Also, I did recently have an alternator go and batteries are not doing as well as I would like them to be doing.

I think this might be my next step as you suggested.

Those two DTCs tell me your EGR valve is not responding quickly enough to the PCM's commands, which is usually caused by carboning up of the valve, and/or sticking turbo VGT. This again, would also be covered under your diesel engine warranty. There is currently a TSB (technical service bulletin) from Ford to address this issue as well, which includes supplying the customer with one bottle each, of PM-22-B and PM-23-B cetane booster and anti-gel additives. I strongly suggest picking up a few of those bottles at the parts counter as well, when you bring your vehicle in to have your other issue addressed, and follow the directions on the bottle pertaining to its use.

Wow impressive. Thank you so much for the info. I will be calling my Ford dealer tomorrow. Thanks.

You know, I'll be honest with you. We did take out the EGR valve to see if that was the case and the EGR valve was clean, maybe a slight film of deposit on it but other than that it was really anything were it would stay open by gunk. In any case, I am dropping it off at my ford dealer and have them deal with it. Thanks again for all your input. I wasn't sure if that was somethign that was covered under the warranty.

Well, I dropped off my truck at the ford dealership. The warranty should cover this work as I have been told. The only thing I have to take care of is the $100.00 warranty deductable. Unless they come back with something else. As soon as I find out, I will let you guys know.

[rickrod99]

Ok so I got a phone call from the dealership and they said that the Fuel Injection Control Module was bad. The good thing is that it is covered under warranty. What I didn't like is that the codes that the truck was showing had nothing to do with that. Anyone care to explain? I am curious about all this.
