my f350 kr drw 2003 is down again ..I hoping some can give some insight to what happened..Monday aug 1 was in campground approx. 50 miles from house ,on way pulling 5th wheel no problem in fact travelling I was getting 13.5 to 14 mpg. pulled in campground shut truck off after a hour or so attempted to start truck,it started but started to shake dove it approx. 100 ft or so with tlr attached and them no power shaking no power,shut it off and friend backed 5th wheel onto site..later on I started up to shown someone in campsite large clouds of white smoke I shut down ..truck will be picked in am aug 3 and go to dealer in my town..what happened??truck was working like a top before..this truck has a 2006 refurbished 6.0 in stalled a year and half ago..the sad sad part is I have on put 3234 kms on this engine approx. 1800 miles or so can anyone shed some light on this problem with thanks Karl webb

 

Do you have any way of checking if you have any codes showing? Don't need CEL on to have codes.

Do you have a Scan Gauge or equiv? to see what coolant/oil temps are? Or see FICM voltages are?

BTW, ANYONE that owns a 6.0 should have SOME way to monitor the engine parameters. If you want someone to help you there are certain things they need to know.

 

sounds like you have a Bad injector


Smell the smoke
Diesel fuel or Sweet smell??


Hows the coolant leval??

 

coolant level ok and oil looks like oil ..truck at dealer now..I am sick of these 6.0..not very realible are they??

 

well a turbo seal may have Blown and be letting oil into the exhaust


do you have oil dripping out the tailpipe


Reliability is dependent on a few things


Skill and quality of work of the mechanic doing the work
There are a bunch of reliability mods to do
Quality of replacement parts do your research cause most things are best OEM however things like alternators are best with certain aftermarket
a lot of Aftermarket parts are Pure JUNK
proper maintenance schedule with proper fluids etc...
tuning without supporting mods
improper tunner or No supporting mods will tear crap up

 

thanks for you imput..don't know about oil out tailpipe truck at dealers going to look at mom in pm..I have had a couple of people say they think its the turbo..but..what would have caused the miss ruff idle? away thanks ...Karl

 

after checking with dealer (as they looked at truck this pm) there are 4 injectors gone cannot find out why this truck is going through injectors as I had one go in apr(this is on this reconditioned engine )injectors were supposed to all ne a year ago..I have 3234kms on the engine around 200 miles. can anyone shed some light on this problem??

 

should read 3234 kms approx. 2000 miles

 

How many miles on the truck?

Injectors do go bad.

How is your Alternator voltage/amp output?

What is your low side and high side voltage on your FICM?

You have kept up on the maintenance right? Flushed the cooling system, changed the fuel filter more then once every few years?

What do you have to monitor live engine vitals?

If you take care of anything that you drive it will take care of you. Drive it into the ground and it will let you know at the worst time!

So if you have 4 injectors go bad and DO NOT have any other issues. Issues like a weak alternator that has damaged your batteries which has hurt your FICM which has hurt your injectors. if that isn't the case...Then you have to ask yourself have you change the oil on regular intervals? What oil filter are you using? Not using FMCO filters......they are the best for the truck.

Are you running a stock tune? Or are you running a hot tune?

So many variables....The 6.0L isn't a beast for the faint of heart with a shallow pocket..

 

the Only thing that Would keep Killing injectors is low fuel press


A ficm would have to Overpower a circuit and fry it
Normaly they under power when FICM go which shouldn't hurt an injector
FICM it just fast pulses of power to shuttle the coil






Maybe ed has some different input as far as a FICM killing injectors

 

how do they check for low fuel pressure...should the tech know this????????????????

 

Yes they can check the fuel pressure, but it really makes a difference when you are into the throttle. Ford came out with an update for the fuel pressure it is called the "blue spring" and ups the pressure about 10 psi. Low fuel pressure, bad fuel, old oil, bad FICM... There are several things that can take injectors out.

Have you had the blue spring update done?

 

dan..no I have not winemaker

 

What defines your "refurbished" designation and by who?

What cylinders the four injector's come from can help to lead to the problem. As stated, could be a low pressure issue, could be a faulty injector taking out the rest on that side of the motor, could be poorly rebuilt or reused injector's, could be the harness bundle of the injector's on one particular side of the motor, ........ Lot of could be's, but if an owner wants a better explanation, or to get a handle on a issue before it becomes a problem, a monitor of the motor sensors should be installed and knowing their function will get you in a better place with less frustration.
