There's no actually Haynes manual for it. There's only the Nissan internal one which they SAY is about $1100 until you actually pony the cash for it, and then they refuse to sell it.
The link above should give you a manual which is a reasonable guide, has a LOT of info, but do NOT follow it blindly. A leaking seal on a fuel filter, for example, will lead you to replacing the entire fuel rail, injectors and filter. The manual really does need a degree of "seen it before" applied to it before it shines.
