check the fuel system.it sounds like its not holding pressure.

Sounds like some of the answers you have are confused about if your car is gas or diesel. It could be the glow plug relay cutting the glow plugs off too soon, the temp sensor for the glow plugs, or your fuel system allowing pressure to leak down after it has sat for a while. Also keep in mind the outside temperture and remember that the colder it is the more it takes to crake the car. If you have the cranking problem on a warm engine it is almost certainly the fuel system leaking down, but if the problem is worse the colder it is (both the engine and the outside temp) then it probably is a temp sensor or a relay problem.

Two things to suggest.... 1 Did you clean up the wiring terminals where the glow plugs connect? If they are ropey then the plugs will not operate. 2 Is the timer unit sending power to the plugs? Put the ignition on and connect a voltmeter between the top of each plug and a good earth in turn. It doesn't sound like a fuel problem as all the smoke is simply what you have managed to pump into the exhaust from 10 seconds of cranking!

Would say that you aren't pre-heating the engine. Diesel engines work by pre-heating the combustion chamber via the glow plugs. Diesel works on compression ignition, meaning it's the pressure on the fuel/air mix that causes it to ignite - unlike a petrol engine which relies on spark ignition. The essential difference is that in a petrol engine on a cold start you apply the choke to allow excess fuel into the chamber to increase the combustibility of the mix, in a diesel engine you pre-heat the chamber to allow the mixture to vapourise correctly.
Glow plugs work by turning the key until you get a light on the dash(normally orange), this is before the key position that turns the engine over. When the light goes out then the engine is pre-heated and should start with no problem.
Unlikely to be a fuel problem if the car runs after extended cranking, if it's a fuel line pressure problem it won't just disappear, but could cut out at any time.
Anyone offering advice, please be sure you know what you are talking about, glow plugs have no place in a petrol engine, and spark plugs no place in a diesel engine. At best you're wasting time and at worst your advice could be dangerous.

Your car has a problem with oil slipping by the rings (of the cylinders) in the engine. It leaves an oil film on the spark plugs and you are trying to ignite oil and gas. After a while there is more gas than oil, so it starts. However, oil still leaks into the plugs and you are burning both oil and gas. When you drive 10 miles or so, the plugs get hot enough to burn off the oil. Burning oil is characteristic of a white film coming out of the exhaust, looks like a white cloud. If you look at the exhaust pipe in the back of the car, and put your finger in the exhaust (with the car cold) and wipe it around the second thing you will find out is your finger turns black. This is the second confirmation you have a oil leak into the cylinders. Soot is characteristic of burning oil.

All so very simple...Do you have a glow-plug warmer?. The reason I say this is on those I have dealt with there was a glow-plug warmer that got them to temperature before actual cranking. Then you hold it for about 1-2 minutes and then crank the engine. Fires right up. You have a damn good engine if its working like you described. Just preheat the glow-plugs and you will be off and going. That is why it settles later...because the excess fuel has burned out AND then the plugs are hot. Get them hot 1st and you will see the difference...Hope this helps

sounds like an air leak in the fuel line from the tank. The fuel pump sucks the fuel up from the tank before squirting it into the injectors. If there's a leak you get an air bubble that has to be cleared before the injectors work properly.
Just like a problem on my old pug

Sounds like a slow meltdown .Poor quality and lackluster respec-ing has built a monster that will consume you from head to toe. Unload this aggrevation now for your very soul is at stake. Take it on the chin and don't look back. Plan to get the next 10 years of transportation nearly fault free.

The fuel pump timing and cold-start system needs to be serviced.

natural aspirate or turbo.?
if You don't have a cloged air filter or a leak of air after turbo.
if You don't have an EGR mal funtioning.
BINGO!!!! EGR is not working properly
