I had the same problem with the same exact kind of truck... it is the fuel injectors take it to your local shop and have them test them

There are square cut seals on the fuel lines to the fuel filter and to the pump.
what happens is these seals may not leak fuel but they will let in air in the fuel line and cause air into your injection pump and will make the engine smoke.
this is you most common problems with this engine.

My truck is blowing white smoke out the tail pipe and I have no power wont go but I can idle around its a 2055 f250 turbo diesel, 300000 kms...litterally just started doing this a couple days ago..now ...


White smoke for a diesel means air in the fuel system. You will have to start at the engine, I start at the line going to the fuel pump. Get some fuel in a can, remove the line to the supply side of the pump and put another line from the can to the pump. If it starts and doesn't smoke , then you have to work your way back to the tank and find the spot that is sucking air. If it doesn't start the I would replace the filter first, check again. There is a possibility that the injector pump is bad, but these don't usually throw white smoke. They just make the engine have very little power or no start.

Engine idles rough and puffs black smoke out exhaust


on petrol engines is caused by excissive rich mixture,on diesels the injectors need servicing as injectors are not atomizing properly the diesel and just dribling excess fuelwhich is the black smoke

7.3 rough idle


Gas or diesel having same problem, I'd start there to confirm fuel pressure . It may be pump running partially when cool, but when it heats up (the pump) it may be cutting out pressure wise. Not uncommon for a fuel pump to pump good when cold, then die once pump heats up from running. Still makes noise, but isn't supplying any or enough pressure.

We think it is the diesel injection pump but not sure


Sounds like not all the glow plugs are working.It should run fairly smooth on a cold start if all of the glow plugs are working..Also you shouldn't drive off on a cold start with a diesel,Its really hard on the motors..At least give them 10 to 15 min on a cold start..The oil in them is a really thick oil and when there drove on a cold start theres no oil lubricating the internal parts and will cause the motor to seize up..You may already no this and dont mean you drive it as soon as you start it i just wanted to let you know..When you get alot of white smoke it could be two things,Theres water in the fuel which will make it not have much power die and smoke..But if it runs fine when its warm theres some bad glow plugs...Hope this helps you and have a great day
