Altima 2001

I have an altima 2001 of 4 cylinders and suddenly he did not want to turn on a mechanic told me that the entire electrical system was well fuses and gasoline pump that I do? I don't know what to do now

First it is the first, you must check because it does not start if it is a lack of spark or fuel or bad comprehensive, once this you tell us and we tell you where to look for, because without data there are many options.

Everything is fine, it has a spark and compression tell me that it is something of programming or the Antela where does the key go, does anyone know about this?

If the immobilisator or anti -theft is activated, it is very cause that everything is good and does not start, try the spare key to see if it starts you

Well if it is like it is very easy if it is up to 2001 Motor 2.4cc The only thing you have to do is see the light of Security ke this cerkita of the control lever lights if it is upper and 2002 engine 2.5 or 3.5 The light goes on the cerkita board of the VIN registration number has to be flazing when putting the ingenition should turn off if it does not do it is a program. I await your answer
