Nissan Marc Motor Cr12 workshop manual

I need to know the diagram since the vehicle Nissan Marcha Motor Cr12 does not start and the signal is cut .. It seems that the crankshaft or camshaft sensor is working badly ... but I wish to know how the diagram is,

thanks and greetings

Hi Henry I see your comment but I want to know what conditions the car arrives, is it sinister or has no keys, or did they fall into the water? I don't start from day to day?, turn on the board? Going,? Do you have fault code? Because the Aut Mar March ignition system depends on the NATS system, and if it is evil or does not work, it stops sending a signal to other components, the first thing that I would do would be to scan and verify failure in the NATS system and if it is not because there is verifying gasoline PRSION, because the electronic ignition works with Can CAN system throughout the system checks and comments and seeing if I can support you in your problem, ok luck
