ok so my truck does the same all the time like it smokes like crazy and its a mixture of white and brown and its really boggy with no power like to much fuel ne ideas????
In indirect injection engines they have a precombustion chamber before the actual cylinder bore. In engines that have higher miles they tend to gather soot in that chamber. It could be that the injector is forming drops and settle in the chamber thus causing it to load up on fuel. Everytime it gets started it smokes a little untill all the bores are clean of excess fuel. Thought that might help you guys out. And yes i agree you guys are all right it could be any of those factors.
I've checked the glowplugs..... They're ok.. I'm pretty sure it's an injection issue..... It throws injector pump failure codes everytime it does this (I.E: every time it's started....)
It goes away after warm up... OR if I punch the accelerator after it starts, it will clear up right away.....
I had a 94, The pump let go. There was black smoke everywhere (idleing you couldnt see the back 3/4 of the box) and the idle was so rough that the box and cab were flexing a good 4 inches.
If it clears when you punch the throttle its shouting glowplugs.
The half firing from one or more cylinders is also screaming glowplugs.
If it did it all the time it would be likely injectors or pump but from cold with no throttle glowplugs are the only thing that can really be wrong with it.
Swap them even if you think they're ok and I bet it cures it.
I've had the glow plugs all out of the truck and put electricity to them on the bench. They all glow...... Also, all new injectors... It was a bad fuel pickup in the tank.... Let the fuel bleed back out of the housing overnight and then I'd end up with air in the fuel when starting for the first time of the day.....
Read first - Dirty injectors will lean out the air/fuel misture, causing a loss of power, rough idle and sometimes, white smoke in the exhaust. White smoke usually occurs when there is not enough heat to burn the fuel. The unburned fuel particles go out the tailpipe an typically produce a rich fuel smell. It's not unusual to see white smoke in the exhaust during cold weather until the engine warms up.
Bad glow plugs or a faulty glow plugs control module can cause white smoke on engine start up. If white smoke is still visible after the engine has warmed up, the engine may have one or more bad injectors, retarded injection timming or a worn injection pump. Low Compression can also be a source of white smoke, as can air in the fuel system
@shadowboy696979 that sounds like bad injectors to me

@fmx4life1011 Easily 20+ with the 6.2/6.5. Fuel-sipping engines if you keep your foot out of them!

Yea man I would try an injector driver module. if it's not that then it's probly the injection pump.

@deerefanatic how did u fix this problem where is this housing where the air would get to the fuel
chulito1234 2 years ago
@deerefanatic Yep, my 6.2 did that. Dropped the tank and the strainer was packed with mud. Starved the IP, you're lucky it didn't kill it.
BTW: This new low-sulfur diesel is hell on that IP and those injectors, make sure to use some additive like Power Service to lubricate everything.
