It does not turn on

I have a problem with Ford Focus 2003 does not turn on only some lines in the tacometer but nothing to turn on

First describe that it has passed before the problem was located and the symptoms of the fault to give you a diagnosis

What happens is that I was checking the fan that does not go down and was testing with another relay and as it made short and turned off the engine I may turn on and does not go and the tacometro only puts pure guines

other ayas voous a fuse eph
another because with the scanner to have to reset it because this when there is a cutting the functions of the memory
the reset does not last more than about 5 min 5 min.
