1Z Engine: Starting Problems & Performance Issues

I've been having a problem with my diesel car since today.

Sometimes, I have to hold the start button for up to a minute before it actually starts.
Furthermore, it sometimes fails to start and produces a lot of smoke.

What could be the reason for that?

Since I'm completely new here, I'd like to ask for your advice!

Best regards,

Bernd.

Try searching for 'crankshaft bolt' and '1Z', and you might find what you're looking for.
