Good evening I have a Nissan Micra Gasolina and I can't start it, I have looked fuses and are correct, the problem is that I turn the key and the typical buzzing is not heard, and I don't know if it could be or the clauses or the gauge pump relay thanks for your collaboration.
To get out of doubt you can connect two direct battery cables to the pump, you will take if it works and if you make it, once we know what the real fault is, that is, a good pump and wiring badly is that we take corrective measures test and letharms.
The problem you have is very likely that it is the gasoline pump usually fails in some models. I imagine that your model is K11 and this one in particular has the pump inside the deposit to make its accommodation you will have to lift the rear seats and remove a lid with three head screws. And another has a clamp that will release it with a pliers, it is from the return, where the tubes will have a 2 -cable connector if you put the contact and arrives current 12v is that the pump is bad if you do not arrive you will have to check the relay that is on top of the fuses if I am not mistaken. I hope this helps you solve your problem.
