The AB member who could help you most is Tonyav. I'm sure he will be around later, just keep an eye on your post, maybe repost your original question later and he will probably see it

It could be many things causing the problem – white smoke is indicative of water getting into at least one of the cylinders (head gasket/cracked cylinder head).

Difficulty in starting could be down to poorly gapped spark plugs.
If the vehicle were mine, I would check the gap on all plugs, which will also give you the opportunity to examine the condition of the plugs – they should appear a light-brown colour (not sooty-black or wet with oil/fuel).

Well anthony, if that's the case a new ( or recon / rebuilt ) cylinder head is required.
