on some diesel engines the glow plugs will cycle after the engine is started. it does sound like your glow plugs are not all working that would cause the hard start and excessive smoke when it does start.

check to see if your brake lights are working.usually the stop light switch fails and is the cause.but before buying a new one check the stop light fuse.its a common problem with a simple fix.hope this helps.

this is a common problem for these cars glow plugs go bad like spark plugs however the smoke would lead to bad mass airflow meter. it is not telling ecu corrcet miss. disconnect mass airflow meter. when cold see if this makes it start better. it should would means you need new m.a.f. glow plug issue take a test light place clamp on positive of battery then pull off glow plug connectors place tip of test light on glow plug the bad one will have a dull light unlike the good one which will be brighter. will need new plugs and wire harness four **** connectors and wire striper and crimper will fix concern good luck

first check glow plugs resistance values, sorry but i cannot tell you what they are supposed to be at offhand.
if the values are correct then you may need to replace the wiring harness which connects to the glow plugs.
more likely to be the plugs themselves though
