SOURCE: sudden whit smoke

it is a blow head gasket. the coolant circulating around in the block is kept out of the cylinder by the head gasket. the coolant burns white and that is what you see out the exhaust pipe. i would recommend not driving the car with this problem because you can hurt other engine parts **** as spark plug and you risk over heating.

SOURCE: slow to start when it does start there is a cloud

If its black smoke, I'd suspect that you either have some leaking injectors or worn valve seals. White smoke would indicate coolant getting into the combustion chambers (head gaskets?) I'd pull a few plugs to see if they have anything on them before starting it up after sitting overnight.
a weak ignition coil or a coolant or manifold air temp sensor can do much the same thing though so I'd do some testing to see what you are dealing with before buying any parts. (check air filter as well...if it's really dirty it can contribute to that.)
You didn't mention any coolant loss or overheating so I'd tend to lean towards the engine getting a rich mixture or one of the other items related to that I mentioned.
Haynes and chilton are decent when it comes to sensor testing instructions and all you need is a digital multi-meter. Fuel pressure gauges are expensive so you may want to consider borrowing or having a shop check pressure for you. (Older gauges for carbureted engines read too low to help)
Good luck

There are two main causes for this, especially given your limo's age:
- a leak, and you would notice little puddles of oil underneath the car
- worn piston rings - this will cause blue smoke from the exhaust, especially after idling for a few minutes
Have someone watch at the back, when the engine is hot, and after idling steadily for a few minutes, rev up suddenly to 2000-3000 RPM.
If you get a big cloud of blue smoke, the engine is worn.

Hyundai Accent 1.5 Diesel. Intermittent problem with starting. Sometimes starts and runs fine. However sometimes on starting car will not run above 750 rpm and throws out HUGE clouds of black smoke. ...

it sounds like a glow plug issue. perhaps a bad glow plug relay. I would think its the relay if the problem comes and goes. If it were a bad glow plug the problem would be constant. check for volts at the glow plugs next time the car acts up. If you find no volts, tap on the glow plug relay next time you turn the key on. This may cause it to activate. if so then replace relay

I have Hyndia Tucson 2006 Deisel. I have a problem in it. This problem is smoke heavily (Black) and there is no intention of any force during press the accelerator.

mean there might be fuel leaking into the engine or the air to deisel ratio is and not atomised correctly. the main causes are normally is the air filter that isnt allowing air into the engine. Fuel filter can also be at fault not allowing enough fuel in or allowing to much in the engine sometimes. This causes the chamber to burn it out. Fuel injector if fualty could allow to much fuel or not enough. My personal suggestion would be to run fuel injector cleaner first, then change the air filter. If that doesn't fix it change the fuel filter. I would go the cheapest route first. Is is prolly something simple

Car won't start when it's cold

Depending on the type of car engine you have, any of these three causes of car start-up failure during ambient cold temperatures may apply to your situation:

And here are the causes of cloud of smoke:
Likely, your cause of smoke has to do with the air control or fuel regulator, as either of these is somewhat responsible for your initial start-up difficulties.

Hope this helps! Brad
