the truck is either an e350 0r f250 right? now which?
Gas powered rigs ? call the dealer to inquire about outstanding recalls. inspect your fuel pressure regulator for the correct number
F4TZ or newer should be seen. check the oil dipstick for a fuel smell. if the spark plugs show excessive fuel or carbon. change the oil first, and the filter. then use an update regulator, and tune up.
diesel rigs? theres a possibility of fuel injector pump and or injector problems. first determine the glow plug system is right. see a diesel tech about what diesel fuel system yours is equipped with, do the required maintenance, and with good parts does it smoke cold only, warm only or both. then you can begin to get answers. several systems were used and engine displacement must be known to look it up. a faulty glow plug controller or inoperative glow plugs can contribute to cold smoke, a faulty injector pump or leaky injectors can cause warm smoke. some diesels have the newer system and there are a series of updates you must have. parts are very expensive so do your homework first. build date, engine size, injector type, outstanding recalls, tsb's tech service messages. these can all be found at the ford dealer. they will be happy to answer your questions.
White smoke is usually a good sign of un-burnt diesel so reading your post and all the things you have already changed ie the glow plugs I would have the injectors tested to make sure they are atomising properly as it sounds to me like when your car isn't under load ie at low revs you have a cylinder that isn't firing correctly
Hope this helps Nick
This could be the FICM or the injectors. If you have a code reader, it can help determine if its the FICM. You can also check out this thread http://www.ford-trucks.com/forums/899444-ficm-testing-procedure.html
You are probably already aware of all the 6.0 problems. It does sound like a fuel issue. The injectors are unfortunately a problem and very sensitive(don't ever run out of gas). If one injector is bad or going bad, truck will run rough at idle but once rpms get up, the truck will seem to run better. When 2 or more injectors go bad, truck will barely run. In either case, power will be very low at lower rpms.
thanks let me know if this helps
could be a number of things from low oil to low batteries. fuel injector control modual or bad injectors are really common on the 6.0l try giving the batteries a slow charge out of the vehicle. could also be a glow plug concern. try plugging the block heater in and see if it has the same effect. most likely fuel injectors or the ficm tho. fuel injectors run about $100 a peice and 3 or so hrs to install and the ficm is around $800 and about 2 hrs to install and needs to be programed by a ford authorized scan tool upon installation
Are you getting good spark? Fuel pump? I know you changed your fuel filters, but can you hear the fuel pump come on when you turn the key just one click - (not all the way to start it)? OR
"There are quite a few things that might be causing your problem but the first thing I would do is have your electrical system checked out. Sometimes a bad alternator can stop charging your battery and cause this kind of problem. Even though the battery has enough voltage to turn things on it might not have enough to start the car. Most auto parts stores will test your electrical system for free. You can also check your battery cable connections and terminals. If they are corroded or loose it can cause this type of problem. There are other things that it could be but that is the most likely."
You can get the wiring diagram at www.alldatadiy.com and it will have all the codes and will have the information to test before you order the parts, also have you replaced the fuel pump? fuel sock? it also has two pumps a primary and the secondary check for fuel rail pressure, to test injector remove injector wire and test with digital ohm meter test the power post of the injector to ground. if it read 5 ohms or less it is ok. Have you checked the glow pulgs and glow plug timer is it stuck on removing power from injectors, need more information to give you a better answer.
hi from uk if you have to turn engine a little longer than normally? on initial start fro cold? and then starts/runs ok for rest of day ? then more than likely your engines glow plugs are in early stage of failing/burning out? these engines rely on pre heat of cylinders when starting especially from cold so they have glow plugs for this purpose indication of burning out is the grey smoke you report on cold starts this is fuel that is not being combusted due to poor cylinder compression/s being heated on first start but when engine heats up no problems so i suggest you renew all 4 glow plugs they are easy diy job and you can purchase from good motor stores not necessarily dealers they are just like spark plugs usually 10 mm socket/spanner to change em after disconnecting the elec supply cable from each hope this helps and inspires you? if milage is high then they are in need of renewal
