New to the site and would like to say sorry in advance as I am sure this same question has been asked numerous times.I own a 2005 f-250 with a 6L diesel and within the last week have noticed it takes longer cranking time for engine to start and within the last couple days when I try to start it the engine will crank and then it will start to crank faster like its going to start then it will fire up sounds like a low rpm for maybe a 1 second then runs fine. I have also noticed that in the mornings when I start the truck it will puff out very little white smoke for a second then clears up. Any help would be greatly appreciated. Thanks

 

Its very hard to say without a scanner hooked up. You need to see the oil psi when cranking. It might be beggining to develope a internal oil leak,low ficm voltage,injector stiction,more symptoms would occur with some of these ive mentioned. Has som1 u know have a auto enginuity scanner? There is just no guessing. Guessing can get expensive very quick. Were are you located? If your close to alabama,i could diagnos it for ya,no charge. Im **** about my truck,if it stumbles or farts diffrent,im tearin the motor down. Theres nothin wrong with paying to much attention to your truck. It saves money

 

Yeah I guess I am going to have to find a good mechanic that I trust. Wish I lived close to you but Illinois is just to damn far from Alabama. haha Thanks for the feedback

 

If you like turning your own wrenches and want to start self diagnosing, a ScanGauge ($) or AutoEngenuity ($$$$$) combined with the guys down in the 6.0L forum will almost definitely solve any problem you can come up with.
